Hello All,

Thanks for your inputs on allowing Nortel VPN. Basically the simplified version would be :

Host in Extranet -> Firewall -> Internet -> Nortel VPN Gateway

Do you need help?

Now, we need to have a correct ports open on Firewall. From the inputs I've received so far :

a. UDP 500
b. IP Protocol 50
c. TCP 57

Did I miss something ?
