I have 10 people who need the ability to dial up a remote modem to connect to a Cisco router (as out-of-band). What device can I place on our LAN that they could telnet/ssh to then dial out? I don't want to run a analog line to each work station - I would like to share resources. Is there some type of Access Server (?) or maybe a card that I install into a router/switch that would allow this.
