I'm a new Tomato user and not sure it is possible to make it do what I want.
I first have my Internet box, acting as a router on 192.168.0.254 (=not bridged), with subnet 192.168.0.0/255.255.255.0 (let's say LAN1); there is no possibility to add any static route on this box.
I then have my E3200 with Tomato, with LAN on 192.168.10.0/255.255.255.0 (let's say LAN2) and WAN IP at 192.168.0.30.
The hosts on LAN2 (behind the E3200) can reach the hosts on LAN1 (behing the box) with the E3200 as gateway; LAN1 —> LAN2 doesn't work, because their gateway (the box) has no route to LAN2, and no way to add one. Too bad, but understandable.
So I'm trying to add a static route on a LAN1 host : route add -net 192.168.10.0 netmask 255.255.255.0 gw 192.168.0.30… and I don't understand why it doesn't make it.
It sounds like E3200 can route LAN2 to LAN1 but cannot LAN1 to LAN2.
LAN1 can ping E3200 on 192.168.0.30, and that's it; I can't even access the Tomato webinterface on it's WAN IP from LAN1.
Is that the right behaviour (and so I would like to learn why), or is there any option I'm forgetting to set?
