We have a FWSM module in 6513 core switch which acts as the gateway between Vlan's.
We have an exhange server (Microsoft Exchange 2003) in one VLAN and now we face a connectivity problem to this server on port 25 from other VLAN's. The port is open and no restrictions are there from Acces-lists.
Once we telnet to the exchange server on port 25 from a different VLAN we get the below given message
220 servername.ourdomain.com Microsoft ESMTP MAIL Service, Version: x.y.wert.yuio ready at Tue, 2 Oct 2007 14:04:34 +0200
--End of Output---
The scenario here is, we have lot of application servers which monitor multiple devices and these application servers sent mail to the exchange server. These application servers are in a different VLAN.
I aint sure what exactly is blocking the return traffic? Someone please advice on this. Thanks.
