hi i have a strange night with our firewall ;) i wanted to utilize the icmp redirect packages to connect our to different networks on the same segment i have a lot of these messages in dmesg: Redirect from 10.0.0.2 on lo about 152.66.235.1 ignored. Advised path = 0.0.0.0 -> 0.0.0.0, tos 00 --- with tcpdump i saw strange packets crawling on the lo interface ;) IP 10.0.0.2 > 0.0.0.0: icmp 104: redirect 0.0.0.0 to host 152.66.235.1 when i look into these packets, there is another icmp redirect with : 0.0.0.0 -> 0.0.0.0 i''ve check many things, the most imports: # ip r g 152.66.235.8 from 157.181.96.1 iif eth0 152.66.235.8 from 157.181.96.1 dev eth0 src 10.0.0.2 cache <src-direct,redirect> mtu 1500 advmss 1460 hoplimit 64 iif eth0 # ip r g 152.66.235.1 152.66.235.1 dev eth0 src 10.0.0.2 cache mtu 1500 advmss 1460 hoplimit 64 i think it should work... our firewall is acting as an arp-proxy on our network, it does some packet filtering and traffic accounting, nothing unusual it runs 2.6.11.8, on another machine(with 2.4.29) which is does nearly the same - everything works fine, and i see those redirect messages... i could drop in a lot of config/sysinfos but i think i missed something very basic... best regard, kirk
