I have 3 office locations. The main office has a RV082 and the two satellite offices have RVS4000's. I would like to have a site-to-site IPSEC VPN from the satellite office to the main office RV082. Other than the configuration detailed in the RVS4000 is there any routing or ports that need to be opened or any other changes I need to make in the configuration? All 3 are on separate 1918 network spaces and there are no overlaps. Will the right and left side see eachother and the general internet without any major fuss? Just checking if anyone has had trouble with these before I do it. Any caveats/details are appreciated. Thanks!
