Backup support access to a router

Thu Mar 08, 2012 4:25 am

I was just thinking about this the other day, iirc I read somewhere about hooking up a dial up modem to the aux port on a router so that if your service failed you could dial the router directly to get access and diagnose faults.

Does anyone still do this? or do you use other methods?

Cause it seems a bit old hat to me and I figured if you are paying a line rental on a phone line why not get dsl as well?

ok lets assume that you can't get dsl for some reason (rats on the line, leaves eating the cabling, solar misalignment or something) Could you still use a modem?

Or what other options would you consider?

hmm on a semi decent isr router just get an add in?

If so how would you look to cofigure it so that the router didn't try to use it in a failure situation but so you could still get in remotely to diagnose router issues?

I still see backup dial access to routers used frequently. If the site has an existing analog phone infrastructure it's a lot cheaper/easier to add a modem and a terminal server.

I have been looking at something like one of Cradlepoint's routers and a 3G or 4G USB device. Trying to get my boss to approve me to get a setup in the office so I can do some testing. My thought was to run a VPN tunnel between the Cradlepoint and our ASA's.

Interesting, then I'm guessing you would only push management subnet traffic down that VPN to prevent any production traffic trying to get down it when there is a failure.

Yep that is the plan. I would only need it to be able to know if I have a hardware/software issue or if it's a circuit/fiber issue.
