Hello. I'm trying to setup a VPN solution for an outfit that has no dsl or T1 access. they have only ISDN. they are using a netgear ISDN modem that does not support VPN passthrough. I'm wanting to find out if there is an ISDN modem/router that has VPN/IPSEC built in. If not, what is the best way to accomplish this? they will be connecting to another location that has DSL and a dlink dsl/vpn router using IPSEC with DES encryption. i've not found an isdn modem/router that will support this. basically, what is the best way to setup a VPN to this location that has only ISDN?
thanks in advance! :)
