TCP port used by the VPN connection

Hi All,

I have a PIX 515E, beside the VPN connection I would like to block all other traffics.

Which TCP port should I open to achieve the above objective.

Thank you

JC

Re: TCP port used by the VPN connection

Hello JC,

Do you want VPN connection from inside to outside or the VPN connection is terminating on the PIX 515 E ??

If you have connections from inside to outside, you just need to open UDP 500 and UDP 4500 for VPN connections. you can deny rest of the traffic.... From outside to inside, the PIX will anyway block all traffic unless you specifically open ports....

Hope this helps... rate replies if found useful...

Re: TCP port used by the VPN connection

Dear Raj,

Thank you very much for your advise, if for some reason, I have a router (2600 series) in front of the PIX, and beside VPN traffic the router need to block all other traffic.

What should I do?

Thank you

JC
