Can anyone please give me a word of advice here please? I need some guidance on setting up a VPN IPSEC. I am hours away from spending big bucks on PIX 501's and upgrading our 1720 Routers. We have two branches with 50 users and 3 branches with less than 10 users. First question, I saw a posting that said that you don't need a router if your are using only one IP? I can agree with that, so will it be far better to nix the 1720's in our smaller offices and just use them in the two larger branches. Larger branches will possibly use several IP's as time goes on? Also does anyone have any experience with win2000 networks functioning fully behind these firewalls and from Lan to Lan? Thanks!!
