Using Net Meeting on company LAN works fine. Cannot get it to work from an outside internet computer coming into the LAN. All pertinent ports are open: 389,522,1503,1720,1731. Also setup one to one NAT from external IP to internal workstation IP. Just want to share applications. Watching my firewall traffic (Watchguard X750e) I see it passing traffic to the internal workstation, but the workstation never replies. Like I said it works fine internally. Ideas?
