Red face Iptables rules to allow user's access M$ Exchange 2010


Hi!

We have setup a Exchange server at remote location and while testing I am facing following issue:

1. While configuring Outlook, it's not able to reach the exchange server which hosted at third party and is reachable from everywhere except my Local Network.
My Local network is as following:

Local Lan On Private subnet - Gate+Firewall(Iptables) with two interfaces(private and pubic)with natting-Internet Connectivity.

Where as Exchange server is setup at a Data Center and accessible from internet.

I need to know that what all rules are required for user's to configure outlook with Exchange 2010.

Rest of the things are working fine (Internet connectivity, Exchange OWA access).

Thanks,
Parveen

Are you performing natting with IPtables or some other device (DSL router etc)

Smile Thanks Working no, This was blocked from ISP end.

Hi!

Thanks for suggesting, but this was blocked from ISP End and now working fine.

TCP Port # 135 was blocked from ISP side which is now open and it's working fine now.

Thanks,
Parveen
