Hello everyone; I have a network of linux machines running RedHat 6.1 and routed. Here is an outlay of the network: (hopefully wrapping won't confuse too much) NETWORK A -> eth0 -> LINUX ROUTER A -> eth1 -> wireless -> eth1 -> LINUX ROUTER MAIN -> eth0 -> NETWORK MAIN 10.11.0.0 10.11.0.1 10.0.0.11 10.0.0.1 190.190.9.1 190.190.0.0 255.255.0.0 255.255.0.0 255.255.0.0 255.255.0.0 255.255.0.0 255.255.0.0 I have about 11 Machines (LINUX ROUTERS A-K) which connect to LINUX ROUTER MAIN in the same manner. Running routed on these machines works perfectly. The Networks all just want to speak to a single machine (190.190.1.1 -- an as/400) and the as/400 wants to speak to various printers in each network (example: PRINTER A 10.11.0.254) Each NETWORK has its own B class network (NETWORK A is 10.11.0.0, NETWORK B is 10.12.0.0, NETWORK C is 10.13.0.0, etc) 190.190.1.1 can ping 10.11.0.254 and 10.11.0.254 can ping 190.190.1.1. The wireless is all bridged (all LINUX ROUTERs eth1 go into a massive 10.0.0.0 network). However, wireless is flaky. I'm looking to set up a backup modem system at each Network when the wireless goes down. I have a script running in cron every minute on LINUX ROUTER A that simply pings 10.0.0.1, if it is missing, it will bring up ppp0 into LINUX ROUTER MAIN. LINUX ROUTER MAIN then assigns it 10.0.0.111 (LINUX ROUTER B gets 10.0.0.112, C 10.0.0.113, etc) as its IP. In LINUX ROUTER A's ip-up.local I have the following: route add -net 190.190.0.0 netmask 255.255.0.0 dev ppp0 route del -host 10.0.0.1 route add default gw 10.0.0.1 dev eth1 (I don't think I need all these as routed should handle this for me). People on NETWORK A can ping 190.190.1.1 just fine. 190.190.1.1 Cannot ping 10.11.0.254 when connected via ppp0. I bring ppp0 down (and plug in the wireless wire) and it works fine. As soon as I unplug the wireless and bring up ppp0, 190.190.1.1 can't ping 10.11.0.254. Any ideas? Suggestions? I've been racking my head over this one for days. More information?
