Praveen,
 
    I deduce you've got RPC over HTTP working. What was the key change?

http://www.MSExchange.org/ 
HI,
 
I got this running now. We are able to connect to exchange 2003 server
behind firewall. I have opened following ports from LAN 1 to Exchange server
LAN: RPC 135, 53590, 1175,1082,NBT, MS-DS. Not sure all these ports are
needed but it started working after opening this. Basicaly i got these ports
from firewall log. 
 
However connectivity is very slow. If i connect from the same LAN as the
exchange server then it is faster, but from the  LAN 1 it is slow. Is it
because traffic has to pass through firewall or is because this particular
LAN do not have ADS, DNS ... Should i install one more GC on this LAN 1 or
is there any other better option.
 
RPC over HTTPS  works only for win xp sp1 with outlook 2003. We have many 2k
OS & old outlook clients also at present and it will take at least two
months to move to outlook 2003.  
 
Regards
Praveen R

What do you mean by different networks?, different domains, different
forests, different subnets etc etc 

 

I would recommend looking at using RPC over HTTP instead of turning your
firewall into swiss cheese.

http://www.MSExchange.org/ 

Hi,

I need to allow users from different network to access my  exchange 2003
server across the firewall. Can you please let me know what are the ports I
need to open to allow MAPI client traffic. 

 

We use chekpoint firewall.

Praveen R
