Hello all , I have this situation I have already Isa Ent installed that worked fine with two Ether Net card one internal and one connected to the cable modem everything worked fine recently I have changed my ext connection to ADSL connection with internal Pci ADSL card and also changed my ether net card to a dual Compaq Net flex card so now I have on my firewall one pci ADSL and one dual net flex Ether card. I have configured my isa to work with the ADSL by adding dialup entry and eventually reconstruct the LAT table from the active connection for the ether net card. now my problem is that all the old ruled that assigned to the SecureNat clients for example (Msn Messenger, http,ftp etc..) before the change of net card config working and if I want to add some new rule for example I have created rule for Edonkey that use primary tcp Outbound 4661 or IRC 6667 won't pass and I am looking on the log for the isa I can see clearly those new rules are BLOCKED. any idea ! Thanks In Advanced
