Have a question which is related to a Draytek Vigor 2820 router (with firewall).
We have set up OWA in our company and it has been working fine. We used to have a Draytek 2600 router and I have configured all the forwarding need for OWA to work. It has been working.
Last week we bought a 2820. I configured it the similar way as I did to the 2600. Internet connection is fine, VPNs are connected, but OWA no longer works. I have double-check every settings and they are very much the same. The only thing different is that on 2820 there is an Advance Setting option, which 2600 don't have. Within the Advance Setting there is an entry for Codepage, Window size and Session timeout.
I haven't changed any of those default settings on the Advance Setting - so they still read :-
Codepage :- ANSI(1251)-Latin I
Window size :- 65535
Session timeout :- 1440 Minute
I don't know if I need to do anything to these values in order to get OWA working on a 2820 router. If I swap the 2600 back in it works straightaway so there shouldn't be a problem with my Exchange server. I believed there must be something I missed out on that 2820 router.
Can anyone please help? Thanks in advance.
