Hi I guess that the session works because an incoming connection from the neighbor is accepted even if outgoing connections fail. I am not sure how GRE tunnels handle TTL in your setting as EBGP is by default one hop. I guess this could be problem in default setting, where TTL is inherited, but with 'ttl 255' it should behave as one hop. You could test it with 'ping -t 1 10.200.206.250 -I 10.200.206.249'. Also note that '-I 10.200.206.249' explicitly specifies dst. interface, not just the source address. Try just 'ping 10.200.206.250', it should work too. Could you send me lists of your routes and interfaces (ip r l, ip a l)? -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santi...@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
