OK, let's go back to the beginning. Linksys ip address (192.168.1.1) <----> Isa External (192.168.1.2) <----> Isa internal ( anything except 192.168.1.0 subnet). When doing the publishing rule 192.168.1.2 should come up as the external, if not then somehow it has been added into the LAT. Check the lat, in fact I would delete it and make sure ONLY the internal subnet appears in there. Leave out the 127....etc. Try that and let us know how you fare.

It doesn't seem to matter if I'm using split DNS or the internal DNS, I continue to get an error stating there are no external IP addresses available. Port 25 is enabled for the server at the router just as ports 80 & 443 are for OWA. Would anyone happen to have any other suggestions on what I can trouble-shoot to resolve this?? tia ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 Exchange Server Resource Site: http://www.msexchange.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: steve@xxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=isalist Report abuse to listadmin@xxxxxxxxxxxxx This E-Mail is confidential.
