I found an intersting thing with tcpdump (testing from 80.79.194.3):

On server1 (not working server):

tcpdump -ennqti eth0 \( arp or icmp \) | grep '80.79.194.3'

00:16:3e:74:66:cc > 00:1b:21:09:04:27, IPv4, length 102: 194.145.200.87 
 > 80.79.194.3: ICMP host 194.145.200.87 unreachable - admin prohibited, 
length 68

On server2 (working server):

-bash-3.2# tcpdump -ennqti eth0 \( arp or icmp \) | grep '80.79.194.3'
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes

(nothing)

So something goes wrong with the traffic..but what precisely?
