Hello,


I'm having a wierd problem with one L2L tunnel that I just can't

seem to solve. Our organization has a Cisco 3030 and we are connecting

to an organization that has a Nortel Contivity. The tunnel itself stays up

without any problems, however sessions within the tunnel seem to just

intermittently 'die' unidirectionally. IE.


When everything is fine;


Host A [CAN] talk to Host C

Host C [CAN] talk to Host A

Host B [CAN] talk to Host C

Host C [CAN] talk to Host B


When things go batty;


Host A [cannot] talk to Host C

Host C [CAN] talk to Host A

Host B [cannot] talk to Host C

Host C [CAN] talk to Host B


or;


Host A [CAN] talk to Host C

Host C [CAN] talk to Host A

Host B [cannot] talk to Host C

Host C [CAN] talk to Host B




I've attached the cisco 3030 log for when this happens;


---------


Any ideas?


Ive checked rekey timeouts, encyrption settings, network lists .. etc


Thanks,

Ben Frost

We seem to have a similar problem here between vpn 3030 and contivity 1400; the tunnel shows but but no traffic is getting out at cisco site (cisco is the initiator).

if you have any solutions please let me know

thanks
