That sounds pretty odd -- Exchange uses TCP and UDP so generally if that
works you have a wide open tunnel. So you should be looking at filtering on
the WAG or incorrect policies on the NS.
So the first thing (as always) is to do a trace on the NS to see what's
actually happening, or if the traffic is actually getting there or not. The
usual...
undebug all
clear dbuf
set ffilter dst-ip 1.1.1.1*
set ffilter src-ip 2.2.2.2**
debug flow basic
<send some traffic to 1.1.1.1* from 2.2.2.2**over the VPN>
undebug all
get dbuf stream
* is the IP of your server for which you want to examine the traffic
** is your source device.
My wild guess is you'll see the exchange taffic, and pings and such, but not
the 445 or the SQL traffic because your WAG think's it's not good Internet
traffic and has filtered it.
I'd suggest not putting it in router mode at all, just put it in as an
access point and hang it off an interface of the 208, do your NAT there
instead. If you don't know how to do this, just connect the 208 interface
to an IP on the trust side of the WAG and set the wireless client gateways
to the 208 IP, that will make it work as a WAP instead of a gateway. That
will hand all control of that zone to the 208.
