How to change the ports for the SSL VPN for UC520?

Unanswered Question
May 14th, 2010

I was setting up a remote teleworker SPA525G and realized that our Server Activesync is communicating on the same ports.  Is there a way to change the ports on the UC520 and the SPA525G?  I would really like to roll this out, but it appears as though I have to choose either the server activesync connection for mobile email or SPA525G remote teleworker SSL VPN.

If there is another way to make this work, or if the SPA525G supports IPSEC VPN, please point me in the right direction.



I have this problem too.

I know that you can change the port number for the SSL VPN on the UC520. Not sure if you can adjust the port number of the SPA525G though. SPA525G definitely doesn't support IPSEC. You might want to look into getting an additional IP address from your carrier.

Hey Cole,

Thanks for the suggestion.  I will try the additional IP if nothing else works.

Does anybody else happen to know if you can change the ports for the SSL VPN on the UC540 and on the SPA525G phones?

I don't think CCA can do this, so you'll need to jump into the CLI. Adjust the following to match your needs:

webvpn gateway NAME

ip address port 8443 

http-redirect port 80

ssl trustpoint TP-self-signed-11234657

Hi Jason,

Sorry for the late reply.  I did not have a chance to spend any more time on this, but it is on the back burner for the future when I have a little extra time.  Were you able to figure out how to do it?  If so, I would love to hear how.
