Cisco ASA 5510 with 2 ISP

Unanswered Question


I have a Cisco ASA 5510 configured and running properly. I want to use another ISP, but this 2nd ISP will be use only for L2L IPSEC VPN traffic.

My question: Is it possible to have 2 ISP active at thesame time but the 2nd ISP will service the L2L IPSEC VPN tunnel only?

Please let me know if this possible.

Thank you in advance.


I have this problem too.

yes this can be done. Just use a separate interface for yor 2nd ISP and do the proper routing.

All IPSec peers and the protected private subnets coming via the 2nd ISP should be routed back via the same 2nd ISP.

Also note that all traffic from the IPSec peers - clear text and encrypted traffic will pass through the 2nd ISP as per the routing.
