Issues with GRE tunnels

David Babiano Rodriguez over 7 years ago

Hi to all,

We have got installed a sophos XG 210 with version 16.05.1 MR-1... We have two GRE tunnels configured, but since the past wednesday, the tunnels are not working... If I make a tcpdump, I'm able to see this:

00:39:55.654984 Port1, IN: IP 10.3.2.5.58156 > 78.129.229.30.80: Flags [S], seq 1403441636, win 8192, options [mss 1460,nop,wscale 8,nop,nop,sackOK], length 0
00:39:55.655012 Port1, OUT: IP 10.3.2.2 > 10.3.2.5: ICMP host 78.129.229.30 unreachable - admin prohibited filter, length 60

Anybody knows what it mean this??? We hasn't modified the rules in the moment when the issue appears... Any idea???

Thanks to all in advance!!

Regards!!

David
