We have an ASA on site that is running VPN connectivity out to the web from head office location. Accordingly, we having nothing plugged into the inside interface just the Outside interface where we interconnect to the web. The ASA is configured with a site to site VPN between sites for mainly remote access and off site syslogging.
We have configured the VPN with the inside network address, in this example 172.24.0.0/24 and the isakmp and Crypto Map bound to the Outside interface. However, when we try to bring up the tunnel we get the message "inside interface down" which we would expect as there is no physical device connected to the ethernet port to bring it up. On IOS routers we can use the command "No autostate" to stop virtual interfaces going down, but how can we fix this problem on the ASA?
Any help appreciated.
