Have configured 2 servers with ASL to verify how hard/easy it is to setup lan to lan vpn. This part went fine. - used nonroutable IP - 192.168.x.x & public vpn ID on one server and non-routable 10.0.x.x. along with 192.168.x.x - vpn from one 192.168 to other 192.168 address.
However, shortly after getting the vpn setup couldn't connect to public ip to test ipsec and pptp access via dialup connection to ISP. Also lost ability to ping past ISP gateway address - tested ping and traceroute from ASL interface/network/tools.
Since we only have one T1, the public address was part of our allocation from ISP. No problem - except couldn't get onto internet from within ASL server -
This morning addtional wierd problems - folks started complaining that internet access down - check netware server running NAT and it was working - then got message that the public IP address on my Win2K SP2 workstation was a duplicate - rebooted workstation - changed IP address - same message - deleted and re-installed NIC from Win2K device manager - My workstation seemed to work fine for roughly 10 minutes then started getting complaints that no one oculd get on ineternet - checked Novell server - public IP down - duplicate address - tried changing address - same error message - then got error message on my workstation.
Shutdown ASL server and everything works - couple of hours now.
Now I've setup NAT for Windows 2000/NT, Netware, and Linux and I've built firewalls and VPNs for all the above. I've never seen anything grab all the public IP addresses whne I'm using static addresses and DHCP is turned off (DHCP was setup to use 192.168.x.x). Any suggestions - I will be removing the 3COM Nics from the Dell Poweredge 1400SC and replacing them as well as rebuilding the ASL servers from scratch - but I really can't afford to have the T1 connection die so I'd appreciate any suggestions as to what to check in the ASL configuration as well.
Thanks
