Outside interface drops 90% of packets after adding third interface
Posted on 2011-09-06
I've got a 5505 ASA that I'm trying to add a second outside port to. Currently it has an inside, and outside port like most ASA setups. I'm trying to 'dual home' the ASA so our VPN users can be moved to the new port's IP and then the first port can be disconnected. I tried adding the port straight in, but it had two issues.
1) I could not ping the gateway of the device connected to that new port.
2) The outside port that worked 100% just before starts losing 80-90% of all packets. It basically becomes unusable.
I removed the second port and everything went back to normal.
Any ideas? I need to get the VPN users moved over the next week before that second T1's contract is up.
