Let's talk about Networking

[Ookii]

Anyone here running VLANs on their home network?  I'm thinking about getting a nice little VLAN setup going but I'm not sure if our Netgear GS108 supports IEEE 802.1Q (It seems as if it might).

[Mrbloodworth]

Not sure if this is the same thing. Or if its really even related. But im going to toss it out anyway.

Hamachi Some friends and i use it a lot for those "LAN over the net" required situations/gamming 

EDIT: Huh, guess it is, its even on the VLAN Wikipedia entry. So this may be an option for you..

[Ookii]

Not really, thanks for trying though 

[Viin]

Why do you want to do a VLAN?

I have a spare Olicom 24-port network switch you can have - if you want to come get it. It will do most things if you wanna play around with networking.

Edit: It's a Crossfire 8720 Layer 3 switch

[Ookii]

I'd pay for shipping 

CoD4 on the PS3 is not coded correctly or something and does not play well with networks.  The method people get it to work "100% of the time" is to turn off all computers on your network, which isn't really feasible in the f13 house.

I set the PS3 to a static IP address and it also has uPnP on so it should open up anything it needs, yet it doesn't work.  I figure if I stick it on its own broadcast domain it won't be able to interfere with anything else on the network so it should work, and it'd be fun to setup my first VLAN anyhow.

Right now I'm going to assign the gateway of the PS3 to be the Ip of the VLAN, and set the gateway of the VLAN to be the gatway of the real LAN interface.  Maybe it'll work, maybe not.

[Viin]

You could try to set that IP as in the DMZ, which may isolate it from the other computers.

Let me see if I have a box I can ship it in.. or if anyone is driving through Denver on their way to AZ can stop by and pick it up.. 

[Ookii]

With pfsense it's basically the same thing. 

Create Optional Interface
Assign subnet
Add firewall rules permitting all to DMZ subnet
Setup NAT to forward required ports to computer ip

I think a VLAN setup would be:

Create Optional Interface (OPT1)
Create VLAN, hook it into the LAN
Associate OPT1 with VLAN1
Assign OPT1 a subnet and a gateway of the LAN (Not sure)
Permit all packets to VLAN subnet
Assign the PS3 a static ip within the subnet and a gateway of the VLAN IP
Magic!

[Viin]

With this switch you can actually assign ports to a specific VLAN, so you don't have to mess with IP address. (If it's an internal IP, it's not like it needs to be unique).

[Ookii]

Yeah I haven't had an actual managed switch before, once you figure out how much it'll cost to ship I'll definitely be interested in taking it off your hands.

[Lantyssa]

If you're going to set your PS3 up behind a router to get a VLAN going, just get a normal router and set it up behind that to see if it works first.  That should isolate it from normal computer traffic and might be all you need before getting fancy.

[Ookii]

More advice, I honor your intentions madam 

[bhodi]

I think you're making it wayyyyy more complicated than it has to be, Ookii. You shouldn't need trunking. That switch doesn't support it, anyway.

What's your router / wireless / NAT device? I run a Buffalo WHR-G125 with DD-WRT hooked up to an identical GS-108, which is also meshed via WDS into my WRT54G downstairs for extra wireless range.

If you've got a device that you can install DD-WRT on, you'll be able to split your vlans out that way. Also, when I upgraded to DD-WRT, my uPnP magically started working - my PS3 works fine behind it.

[Ookii]

Someone who finally gets it! 

I'm cool except I want the price of shipping for Viin's switch.

[bhodi]

I forgot to mention that I split off wireless and wired into their own vlans on the buffalo itself and use iptables to limit wireless capability. I'm paranoid, even with MAC whitelisting and AES.

A Layer 3 managed switch is going to give you what you want, but I still think you're going overboard. You still haven't said what your front device is, is it a bridge or a router?

So anyway, if you need any configuration help, let me know. I did networking and stuffs for a while. Sounds like Viin knows his stuff too. Best of luck :)

[JWIV]

Did this tonight while waiting for paint to dry.

Followed the directions on the scorpiontek.org site for a linksys wrt54gs v6 and it worked like a champ.    Much like Bhodi, it also resolved my UPnP issue.

I think I'll segues from this thread instead of starting my own with a networking problem. We've got DSL through AT&T and have been using a wireless D-Link router for the last year. I'd been having the router initiate the PPPoE session instead of the modem and everything was working find and then it just stopped. If the modem does the PPPoE and hooked up to one computer it works. If I bypass it on the modem and let my computer do it it works as well. As soon as I add in the router nothing works, like the modem doesn't exist. In the router config it just stays at "PPPoE connecting".

Have a D-Link, a Netgear and two Linksys routers and I'm having the same issue with all of them. Is there something I'm missing here?

[Engels]

I don't know anymore, but often times DSL providers require you to use their particularly configured modem to 'decode' the signal. Using your own router may be the issue. I know it worked for you in the past, but who's to say AT&T hasn't changed the code so that you have to use their hardware?

Also, why aren't you just using the modem to initiate PPPoE, then send that to the router?

[MuffinMan]

I've tried to set the modem to do the PPPoE but once I connect the router nothing happens. No connection to the internet. It's like the router's not seeing the modem or getting anything from it.

[Engels]

I dunno about yours, but my DSL modem is a modem on the front end, but really just a router on the back end. The RJ-45 jack that you plug into either your computer or the router can be set to a static IP, and then have the router set to recieve on the front end with that static IP, then give out DHCP on the back end on a different subnet. Something like this:

External IP: yada.yada.yada.yada (random IP number assigned to you by your ISP)
Internal modem IP address from a static setting: 192.128.0.1 (handmade subnet)
External router IP address gateway 192.168.0.1
Internal router IP address from either static settings or a dhcp pool: 192.168.1.1 (different hand made subnet)

Basically you have to tell your router where your intertubes are coming from, in this case, the DSL modem's internal LAN's IP address, 192.168.0.1

Maybe this is obvious stuff, but I thought I'd throw it out there.

I'm assuming you've power-cycled the modem AND the router? Sometimes you'll get some stale info that lingers, preventing a connection. I usually have to reboot both (together) about once every two weeks or so.

Are you getting activity lights when the router is attempting to establish a PPPoE connection?

Might check with your IP to ensure they didn't change configurations --- your PC might be setting things dynamically while your router is setting them statically.

[MuffinMan]

Does the IP I assign manually to the router have to be on a different subnet than the modem is on/giving it? I just changed the router's IP to 192.168.0.1 instead of 192.168.1.1, modem is giving it 192.168.1.64 and now everything is working like a charm.

[Lantyssa]

It's possible the modem is trying to be 192.168.1.1 which would conflict.  Without seeing a diagram of your boxes and what you have assigning where, I can't say though.

Possibly your ISP uses MAC authentication and it's looking for the MAC of your PC (which works fine when connected on it's own).  Have you tried cloning the PC MAC address in the router config?

[MuffinMan]

The modem's IP is 192.168.1.254 so I gave the router an IP on a different subnet and let the modem do PPPoE and it's all working now. No more passing one cable around to roomates. Thanks to everybody that helped.

[Engels]

Ya, basically, that's what happened. Your modem was using 192.168.1.x subnet as a LAN that was forwarded to your router, which of course would need a different subnet on its own LAN, which is what you assigned (192.168.0.x). Hence no conflict.
