I have been running a Cisco 837 router as my internal network gateway for about 6 months now and it is rock solid - unlike the Draytek 2600 I had previously!
Whilst I've been very pleased with the 837 I am new to Cisco so I want to make sure that if I'm recommending the 837 to my clients I understand what is free and what costs money.
I managed to install SDM to replace CWRS and have IOS 12.2 (14.5)T installed. I registered with Cisco's website and have limited access to a few protected resources it would appear.
Specifically, I would like to understand about upgrades to IOS, support for configuration problems etc. Finally, I am using NAT on the existing 837 with VPN passthrough to Windows 2003 Server running RRAS as a VPN endpoint. Some of my clients run Windows workgroups (no server) and so I'd like to know how good the 837 is acting as a VPN endpoint itself. How do VPN clients get authorised without RADIUS? Also, is it necessary to use Cisco's Easy VPN Client software or can I use Windows 2000 / XP Professional as the client?
