List, I am interested to find out how people are backing up their ADSL connections to the Internet. Currently if ADSL fails we are enabling a demand dial route to the Internet through ISDN and applying the 0.0.0.0/0.0.0.0 static route to this demand dial route. This gives us web browsing capability, but only thorough Proxy. Secure NAT will not function as ISA does not see the dial up connection as it External Address. Has anybody thought of a way around this problem? Anthony Sullivan
