PIX-515E Default routing and cryptos

Nov 05, 2007 4 Replies

Afternoon All,



I am having a problem setting up a PIX-515E which has three interfaces: - inside (LAN) - outside (1st ISP) - outside_eclipse (2nd ISP)



As you can see from the attached config I have added both outside interfaces to the NAT pool, so static routing defines which traffic should be pumped out and natted to which interface. I have placed static routes for all the crypto peers to go out the outside interface.



When I change the default route to route outside_eclipse 0.0.0.0 0.0.0.0


Do a search in this newsgroup for the subject "ASA routing decision" posted on Oct 25th. , you'll find your answer.

Basically you need to route all your peer internal subnets on your outside so they can hit the crypto-map. When you change the default gateway, the packets tries to go out through the outside_eclipse interface so they never reach the crypto map.

Add

route outside_eclipse [peer internal ip subnet] [outside_eclipse gw]

then switch your default gateway and you should be fine

Thats what I was afraid of. Thanks for your advice.
