routing troubles w/ 3 interfaces - Guest - 2004-02-29
I've got a slackware 9.1 box w/ 3 interfaces
192.168.200.1 eth0 internal lan
192.168.0.10 eth1 external lan (has access to net connection thru cable router)
10.100.200.1 tr0 internal lan
trying to route between all three lans (no restrictions).
both internal lans can ping all addresses owned by the router.
hosts on the external lan cannot ping either of the internal interfaces.
no hosts can be pinged thru the router from any of the 3 networks.
looks terrible in HTML but here's my routing table.
#route
Dest - Gateway - Genmask - Flags - Metric - Ref - Use - IFace
192.168.200.0 - * - 255.255.255.0 - U - 0 0 0 - eth0
192.168.0.0 - * - 255.255.255.0 - U - 0 0 0 - eth1
10.100.200.0 - * - 255.255.255.0 - U - 0 0 0 - tr0
loopback - * - 255.0.0.0 - U - 0 0 0 - lo
default - 192.168.0.10 - 0.0.0.0 - UG - 0 0 0 - eth1
any ideas on what's missing?
maybe some other service that needs to be enabled or something..

have you checked your firewall settings (iptables)
maybe thats blocking the pings ?

Quote:have you checked your firewall settings (iptables)IRT routing, sry I can't offer anything, but the mention of iptables in the response caught my attention...... I'm sure I will be looking in here for some advice on that subject especially if it impacts WINE....

Iptables wasn't enabled (to my knowledge).
is it necessary to use iptables when routing?
there isn't any need for firewalling in this project.
thanks for the suggestion.

I just realized why i'm having the ping problems i mentioned.
the two internal interfaces are being fed thru dhcp and are getting the router as a gateway addr while the other lan was getting it's gw addy from the cablemodem router.
is it possible to forward packets thru the router without having to worry about the gateway setting? set two gateways, or set some sort of host setting?
