I have an a single exchange 2003 box sitting behind the firewall.This is the only mail and AD server. I recently configure my user with VPN access. I have problem getting the user outlook 2003 client connected to my exchange server via exchange method(Mapi) through the VPN session. There iis no problem at all when connnting internally. I know this is the firewall port issue, as when I allow all service ports to allow through the vpn session to my exchnage erver , it will have no problem at all As I need to fine tune my firewall to close up all unnessary ports. can someone able to let me know the minimum port require to open out for outlook to connect to exchange server behind the firewall.

The VPN establishes the connection and extends the internal network through the firewall. There isn't any additional port opening to be done. Clearly you have a problem but at this stage you need to work with the VPN vendor to troubleshoot this.

I'm wondering if the VPN / Firewall configuration is wrong. There is something you didn't do correctly on the VPN or firewall. Either they are misconfigured or your VPN in not installed in the right place on your network.

In addition to the other replies (with which I agree), note that RPC over HTTP is much superior to VPN for this purpose....

Dear Lanwench, Tks for the info Is the below link sufficent for me to configure RPC over http on a single box exchange without having a frontend, backend server and ISA server, Or do you have other document link that can guide me through setting up rpc over http on a single exchange box environment http://www.msexchange.org/tutorials/Outlook_2003_Connect_Exchange_2003.html "Lanwench [MVP - Exchange]" wrote in message news:%23rJFLaRqIHA.524@TK2MSFTNGP05.phx.gbl... > news.microsoft.com wrote: >> I have an a single exchange 2003 box sitting behind the >> firewall.This is the only mail and AD server. >> >> I recently configure my user with VPN access. >> >> I have problem getting the user outlook 2003 client connected to my >> exchange server via exchange method(Mapi) through the VPN session. >> There iis no problem at all when connnting internally. >> >> I know this is the firewall port issue, as when I allow all service >> ports to allow through the vpn session to my exchnage erver , it will >> have no problem at all >> >> As I need to fine tune my firewall to close up all unnessary ports. >> >> can someone able to let me know the minimum port require to open out >> for outlook to connect to exchange server behind the firewall. > > In addition to the other replies (with which I agree), note that RPC over > HTTP is much superior to VPN for this purpose.... > > These may help: > > http://www.msexchange.org/tutorials/2003exchangerpc.html > http://www.msexchange.org/tutorials/outlookrpchttp.html > http://www.msexchange.org/tutorials/Configuring-Exchange2003-HTTP-Remote-Access.html > and > http://www.msexchange.org/tutorials/Outlook_2003_Connect_Exchange_2003.html > > > >
