Hello all, after reinstalling Isa-server with sp 1(trial was expired) I run into probs with using dynDNS.com's DNS-updater program. I ever get a "connection error" message. I tried: packet filter userdefined IP proto.: all dest.: outgoing [AND tried both] local comp: standard ip on external network remote comp.: all mode: granted ------------------------------------------------------------- In this small program there are no setup options like use proxy or which network interace etc. I can run the prog from a client computer and this way it works, but this will result in updating a wrong IP (the local network IP). Besides I changed the motherboard and had to reconfigure the networkcards. I gave them the old IPs: 192.168.0.1=Lan and 192.168.1.1=to DSL resulting in warnings that say that there will be problems when reinstalling the old networkcard. Any hints for me?? wkr: Wilhelm Pieper
