Hi, I have a server with two networks interfaces: eth0(IPv4 address 10.10.10.73) and eth1(IPv4 address 192.168.1.16). In addition, there is a following static route in this server "main" table: # ip route show 172.16.0.0/24 172.16.0.0/24 via 192.168.1.252 dev eth1 src 192.168.1.16 # Now when I send an ICMP "echo request" message from 172.16.0.0/24 network to IP address 10.10.10.73, then it is sent out via eth1 interface because of this static route. According to "ip route get 172.16.0.0" the source IP should be 192.168.1.16. However, when I tcpdump ICMP traffic on eth1 interface, then I can see that source IP is actually 10.10.10.73. Why is that so? When I read the http://linux-ip.net/html/routing-saddr-selection.html, then it says that "kernel will use the src hint from the chosen route path" which in this case is 192.168.1.16. Or is the first rule that if it is a reply package, then source IP is always the one which initial package was addressed to? thanks, Martin -- To unsubscribe from this list: send the line "unsubscribe lartc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
