With DSL Modem Speed Touch 510 V4. I want to give VPN access to my users for accessing e-mails, but the thing is whenever I am giving static IP to my external network card of ISA server I can ping it internally not from outside. I tired to make NAT on DSL modem but it is not working, I tried to do many things to access that IP from outside but I can't. I thought some thing wrong with my ISA server means it is blocking outside traffic to access it, so I tried with a window XP PC with two network cards and I gave static IP to external card, but same result. One more thing is that I am sure this IP is working. Can any one help me in this, I will be very much thankful to you.
