I have installed Windows server standard 2008 R2(64bit) on IBM server,on first lan card I have switch and all xp based machines are connected and on other lan card I have connected live IP direct lan cable from ISP ,Also I have configured VPN server on the same IBM server ,I have shared internet connection through LIVE IP ,On server and Lan machines internet and Drive sharing works fine,even VPN client also works fine.I have opened port 80 as I want to have some web services to run over Live IP but Live IP does not ping externally,please guide what should be the issue.
Thanks
Ravi
