Need dd-wrt/VLAN help !

post #1 of 8
Thread Starter 
Hey all, successfully flashed my router to the newest release of dd-wrt. I am trying to set up some VLAN's, did the command line config, but the problem I have run into is that the router's IP is set to say 192.168.10.1 and I have other VLAN's 192.168.20.1 and 192.168.30.1

My problem is that when trying to connect a PC to one of the other vlans, it will not connect properly, no internet connection, cant even ping router. Is there something that has to be done so the router can communicate with all the VLAN's?

Any insight would be awesome, cheers

Is there a reason why you need to use VLAN in a home setting?

Because There are a bunch of computers at my house right now, and I would like to try and get this working, have them on different networks/LAN's and see if it is doable which I thought it was.

Before I was using untangle with 5 network cards, but so far untangle has been pretty unreliable and causing a lot of problems. Trying to see if this will end up being better to use than untangle.

As long as you have the IP and subnet set on each interface you should be good. It sounds as if you are statically assigning IP's on each computer.
so example
Internet connection is 10.10.10.1
Interface 1
VLAN 1
IP 192.168.10.1 255.255.255.0
!
Interface 2
VLAN 2
IP 192.168.20.1 255.255.255.0
!
Interface 3
VLAN 3
IP 192.168.30.1 255.255.255.0

Computer 1
IP address 192.168.10.2
subnet 255.255.255.0
Default Gateway 192.168.10.1

Computer 2
IP address 192.168.20.2
subnet 255.255.255.0
Default Gateway 192.168.20.1

Computer 3
IP address 192.168.30.2
subnet 255.255.255.0
Default Gateway 192.168.30.1

Those configs should allow each computer to now have access to the internet and each other, unless you have ACL's in place that are denying 1 VLAN to talk to another.

Yeah, all static IP's. There are separate dhcp servers on each vlan. The problem I am having is not being able to ping the gateway address from a computer on each vlan.

Example,
VLAN 2 10.10.20.1
Computer IP 10.10.20.100
Unable to ping the gateway/router, when I go into the dd-wrt console, it is showing a router IP of the first VLAN. so only the VLAN1 is responding to the router. not sure if this is a dd-wrt issue or my specific router can't handle vlan's properly, or if there needs to be some extra routing I haven't accounted for.

you have to have an IP for each VLAN on the router. It is just an assumption that you have 1 now. Does your router give you the ability to assign an IP per interface and assign that interface to the appropriate VLAN?

Not that I have seen, I will dig around a bit more.

Are you saying that there should be an IP for each interface? because that would solve the problem
