VPN Solutions

[karlrobertbailey at googlemail.com (Karl Bailey)]

We currently have a cross site cluster SSL based VPN solution that has
reached the end of life, the vendor has told us we?d need to spend ?25k+ to
bring the solution up to scratch & give us a 100 user license (we have 500
employees & found that during the current bad weather in the UK the 100
users JUST covers us) ... It doesn?t do anything to special:

* AD integration. 
* Authenticate on groups
* Security based on groups.
* We also carry out a level of host checking (ie: does the host have a virus
checker & is the virus DB up to date).

It would also be good if it was cross site (ie: if one site goes down the
other site takes the load, we do this currently with DNS & really low TTL?s
then remove the dns record of the broken site)

I?d like to replace this with something we can sick time into getting right
rather than spending the budget on hardware... I?m looking at openVPN ...
Any other suggestions / bright ideas??

Regards
Karl
