We're currently setting up an SR520 for one of our satellite offices. Previously we always just bought ASAs and set up site-to-site VPNs via ASDM. However, since there's only a few people at this site, there wasn't really as much of a need. So instead we got an SR520 used CCA to get the basic settings plugged in so users can get out to the internet.
I do however need to set up a VPN tunnel between the SR520 and our corporate-side ASA 5510 - preferably through as much use of a GUI as possible. I've tried setting our ASA up as an Easy VPN server, but it seems that ASDM only allows you to do that with a 5505. Any suggestions?
