IPSec over TCP using Cisco VPN Client

Hi All,

I have a request from a customer asking me to enable IPSec over TCP on port 443 to connect to the VPN concentrator using Cisco VPN client. The default port used is port 10000 for IPSec over TCP. Will there be any implications on using standard port like 443?

Re: IPSec over TCP using Cisco VPN Client

I've been using that configuration for quite some time now with no problems. Just remember to set it up in both the concentrator and the clients.


Re: IPSec over TCP using Cisco VPN Client

it may conflict with the remote access to the concentrator via ssh.

e.g. when you are at home and want to modify some settings on the concentrator, you can https:///admin

since the https default port is 443, after you modify the ipsec over tcp with port 443, you may no longer remote access the concetrator via ssh.

to resolve the issue, you will need to modify the https management port. if you are not going to remote access to the concentrator via ssh, then you don't have to worry about it.
