I am setting up a second network interface on a static IP and its not working as it should.
I am able to make outbound connections without any problem like
ping -i 188.8.131.52
but when an external ip pings my server I receive the packet but the reply says unreachable
tcpdump -i eth1 08:23:50.427576 IP external.com > 44c3e65d.static: ICMP echo request, id 65388, seq 0, length 64 08:53:55.084512 arp who-has 44c3e65d.static tell 44c3e65a.static 08:53:55.084518 arp reply 44c3e65d.static is-at 00:15:17:27:80:e1 (oui Unknown) 08:23:50.428775 44c3e65a.static > 44c3e65d.static: ICMP external.com protocol 1 port 63628 unreachable, length 92
I also see a lot of this in my tcpdump
08:54:47.404489 802.1d config 8000.00:1c:57:f1:10:8a.8002 root 8000.00:1c:57:f1:10:8a pathcost 0 age 0 max 20 hello 2 fdelay 15
I don't have iptables turned on and if I ping that static ip from another computer on my internal network it works just fine.
I am not a sysadmin so I am not quite sure how to go about troubleshooting this. I would appreciate any help :)
