Load Balancing with secondary tables (not main as in the howto)
Hello, We have 3 DSL connections connected to eth3 and another interface with a dedicated link in eth0 (main table) We want to balance selected traffic (using fwmark and iptables) through our 3 DSL connections in a secondary table named DSL (without using the dedicated link in eth0), but the next command is not accepted, and gives us the follow...

Firewall.routing configuration problems
...or my college. There are two different types of users; students and conference guests, and they have IPs statically assigned by DHCP, from separate ranges (but they are on the same subnet). The students go out onto an academic connection (via eth0), and conference guests go out on an ADSL line (via eth3). eth1 and eth2 are configured for internal use. My question is this (and I''m not 100% sure if it''s a firewall or routing issue, hence the post to both mailing lists). I have some firewall rules in place which direct packets out to a specific ethernet device, depending on the IP...

Hi, Apologies for the cross-posting; I''m not sure whether this is a firewall or routing issue, or both! I have four network cards, detailed below. eth0 and eth3 connect to my ISPs, and eth1 and eth2 connect to local networks. I want to route all traffic from eth2 to eth0, and from eth1 to eth3.

Public Router using Private Links
I am running a public core router using private links from my provider. Details: RH7.3 9 interfaces (all Intel) eth0 is default gateway and has a private IP address all other interfaces are links to other routers or networks eth3 has a public IP address The core router will rarely need to access sites out on the internet, but when it does it cannot get there because the eth0 has a private IP address. Is there a way to force the router to use the ip address from eth3 to access sites on the internet? If so, how would I route...

BUG? re-ordering of tos routes in table
It seems like tos should be considered when sorting routes on insertion. Consider this out-of-order route creation: # ip route add 220.127.116.11/24 table 3 nexthop via 192.168.0.23 # ip route add 18.104.22.168/32 table 3 nexthop via 192.168.0.24 # ip route show table 3 22.214.171.124 via 192.168.0.24 dev eth3 126.96.36.199/24 via 192.168.0.23 dev eth3 ok... it''s re-ordered the routes - it makes sense, the host route would have been masked by the net route, but what about this: # ip route add 188.8.131.52/24 tos 0x15 table 3 nexthop via 192.168.0.23 # ip route add 184.108.40.206/32 table 3 nexthop v...
