Site to site VPN using 3G USB Modem

[umakanthreddy]

Using 3G USB modem on a Cisco router 2911 can you establish site to site VPN?

I don't have personal experience with USB 3G modems on Cisco routers, but I do know that you can configure VPN L2L tunnels over 3G connections with the Cisco 880G series (800 series router with 3G module).

It's possible that a 3G USB modem isn't even supported by the router, the USB port is for as far as I know only for USB flash drives and security tokens

Configuring a site to site VPN tunnel is not that hard, you can find plenty of information about this subject on the internet

About the USB port on Cisco Routers: They only support Cisco USB flash memory modules and the Aladdin USB eToken Pro key See the following document for more information: http://www.cisco.com/en/US/docs/routers/access/2800/hardware/notes/mithril.html#wp35108
