Dear list, I want to switch to another ISP and as I have a server, i have to run the machine for a while on two completely different IPs (with different gateways). I managed to get the system up with: eth1 = old IP Adress eth2 = new IP Adress standard gateway = gateway of eth1 if i come from inside my machine, everything works OK: ping to IP within new IP-Range: the ping goes across eth2 ping to any other IP-Adress: the ping goes across eth1 BUT: If I ping from an extern machine, I can only reach eth1 If I try to ping eth2 from extern I get following lines in my firewall log: Packet log: input ACCEPT eth2 PROTO=1 129.27.115.31:8 62.99.248.227:0 L=84 S=0x00 I=6768 F=0x0000 T=58 (#16) martian source 1f731b81 for e3f8633e, dev eth2 ll header: 00 4f 49 06 b6 f3 00 a0 c5 47 9e 6a 08 00 -> martian source ... that means, that the firewall does expect a package with this source IP adress via this route ... On the other hand, if I ping eth2 from within our subnet of the new provider it works and if I ping eth1 from here i get the same situation vice versa ... any idea how to handle this?
