Hi!

I've setup Cisco Call-Home with e-mail alerting previously, but the email server was on the inside interface of the ASA. For a few sites, the email server is across a site-to-site VPN connection.  Do you know what I have to do to setup to get the asa call-home to see the proper route across the tunnel? Any host on the inside network of the asa can ping the email server across the asa vpn tunnel.


call-home send alert-group configuration profile ConfigBackup-1

INFO: Sending configuration message to asa@123.org...
ERROR: Connecting to SMTP server x.x.x.101 failed: CONNECT_FAILED(33)
ERROR: Failed: CONNECT_FAILED(33)

====================================================


Result of the command: "ping 10.35.208.101"

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to x.x.x.101, timeout is 2 seconds:
?????
Success rate is 0 percent (0/5)

Result of the command: "ping inside x.x.x.101"

Type escape sequence to abort.

Success rate is 80 percent (4/5), round-trip min/avg/max = 1/3/10 ms

I think you need to add the external IP of the ASA to the crypto map so traffic originating from the ASA is also being sent over the VPN. By default the ASA uses the outgoing interface IP as source, thus it needs to be in the cryptomap.
