1 - Private LAN
2 - Cable modem (for internet access)
3 - ISDN modem (for web hosting)
I set up the machine to have 2 default gateways so local traffic for the Internet goes through the cable modem (since it is the first default) and traffic inbound for a domain name comes in on the ISDN line and goes out through the ISDN line. I was surprised that it works this way, but it works great!
Problem: Sometimes the main default for the system switches unexpectadly to the ISDN modem instead of the cable modem (as it was setup).
Any ideas on how can I stop it from switching?
