Happy Holidays everyone!
I'm in a jam here and cannot figure out what the heck is happening.
Configuration:
I have an internal LAN, with all servers running W2K Server and am running WinRoute Pro (WRP) 4.2.5 on a multihomed server, with one NIC going out to the ISP. One server is the primary AD for W2K network and is DNS. Another is a file server W/ WINS, the other is dev server for .NET and FTP and another is HTTP with host headers enabled. A laptop and two workstations running XPpro.
What Is Working:
I can resolve all internal addresses, access the internet, EXTERNALLY access all of the web sites running on internal web server (via host headers), FTP into the network, Term Serv into the network, and internal DNS is working (I know this because I can do NSLOOKUP with no errors to addresses and URLs). I CAN ping the external IP on the public interface as well as ping ALL other interfaces INTERNALLY.
What Isn't Working:
I cannot ping any address outside my LAN with the exception of the external IP from my ISP, even from the WRP server. I cannot access mail from ISP (Comcast), when I could before. I cannot access external SMTP or POP3 from my ISP anymore. THis is a REAL problem because not only do I need the mail, but one of the web sites on the internal web server is running Persits ASPEmail component which requires SMTP outbound access in order to send the email form on the web page.
What Happened:
Was adding packet filter rules and port mapping to allow for VNC, and FTP access to specific servers. All of a sudden I could no longer SMTP out from ANY of the machines.
So everything works except for SMTP outbound and the ability to PING out of the network. I need to be able to ping SMTP.COMCAST.NET and any other address from any machine on the network.
Filter Rules Set on WRP Server TRAFFICOP:
Outgoing Tab: Public Network
TCP open on any address
UDP open on any address
IP open on any address
Outgoing Tab: Private LAN
Same thing
Incoming Tab: Public Network
TCP any host to ports 21, 23, 53, 80, 110, 118, 123, 156, 513, 3389, 5800-5900
UDP any host to ports 53, 118
IP any host CLOSED
Incoming Tab: Private LAN
IP any host open
I've mapped ports to the internal servers on ports 21, 53, 80, 118, 3389 and 5800/5900.
Like I said, all other services are working fine, but I cannot Ping out nor can I send (SMTP) or receive (POP3) mail from my ISP any longer (remember, I can ping the ISP-assigned address on my public NIC).
I've been as detailed as I can get on this. Please, I need help FAST!! My LAN's in trouble without this problem solved!!
Technology is a lot like love. You can shape it and develop it; but it's useless until you share it. Word.
