Can ping from outside, just not inside

Unanswered Question
Apr 15th, 2009

I can ping from Server 1 on Subnet A, across the WAN, to Server 2 on Subnet B with no problems. Full response, no lost packets. But when I try to ping Server 2 on Subnet B from Server 3 on Subnet B, I get a reply on the first packet, then the rest time out.

At first I thought it was a Server 2008 thing, but I have the same issue trying to reach my Server 2003 box. I have replaced the switch, but I'm getting the same errors.

Hi:


Please make sure that each box on subnet B has the same network mask configuration.


What kind of switch are you using?

Please verify the integrity of the servers NIC connections to the switchports. Check for erros on the switchports, too.


Check the log of the switch for more clues...
