     crypto ctcp port 443

It dows not worked. I use IOS version c1841-advsecurityk9-mz.124-25b.bin. It seems that I need newer version.

Hi Peter,

yes that is correct, you need 12.4(9)T or later.

Is it true that if I configure ctcp to listen on port 443 all communication traffic will be on this port?

Correct, there will be no UDP500, no UDP4500, no ESP, only TCP443.

Of course, you need to configure the client to use this port, it does not "auto-discover" the port.

The problem is that one of the clients is behind firewall which filters most of the ports. I will try with more recent version of IOS. I hope that this will solve the problem.

If this don't work is there othere solution? Maybe SSL VPN?

Thank you!
