I have a weird problem with ssh configuration on ASA. We have VPN established between 2 ASA's. I configured ssh to the remote ASA's outside interface. I had troubles with ssh unless I regenerated the keys. Now, on local ASA I have configured NAT so that when ssh to the remote ASA to translate local IP addresses to local ASA's outside address. Since that I can not ssh to remote ASA. My ssh client says:
Connecting to host 10.254.17.10:22...
I had the same message before I regenerated the keys for the first time. No it doesnt help either. If I remove NAT, everything works fine.
Here my config of local ASA:
