well… i have about 40 linksys befvp41 and 10 netgear fvs318v3 connected to pfsense box. besides minor missconfiguration problems everything work fine.
Wow, so they're actually stable? I cringe at the thought of supporting 40 Linksys VPN boxes. ;D I've tried the BEFVP41, granted it was probably 5 years ago, but at the time it didn't work reliably at all no matter what I connected it to.
I think I still have it on a shelf around here somewhere, maybe it's time to give it another shot if for nothing other than the sake of documenting the proper way to configure one to connect to pfsense.
