I don't know what type of setup your Cisco 675 has for routing traffic to you. I'm using a routed subnet in ppp mode. I have the web interface disabled, restricted to a dummy IP address, and the port set to a different number. I selected an unused low number port from IANA TCP port lists. The only reboot I've had to do was on July 19th when the configuration didn't yet have the web port changed and IP address restriction set. I'm running CBOS 2.1.?.

You could set it listen only to some 10 net address. > Good thing my webserver isn't critical, though I suspect there are plenty > of folks who require their webservers to be alive behind their 675...small > business customers, etc... A number of systems I touch often are having sporatic outtages. I'd try them and I wouldn't get replies back and 5 to 10 minutes latter they are reachable again. What I'm wondering is how many of the bigger Cisco routers (and other types) are crashing taking hole segments of the net off line? -- | Bryan Andersen | bryanat_private | http://www.nerdvest.com | | Buzzwords are like annoying little flies that deserve to be swatted. | | -Bryan Andersen | ---------------------------------------------------------------------------- This list is provided by the SecurityFocus ARIS analyzer service.
