PPTP and Cisco Routers
Posted on 2006-03-25
I have soem customers that are using PPTP and Cisco routers to do a VPN to thier network. None of them want to pay for the Cisco VPN client, which i'm told they either have to smartnet contact on thier equipment to get, or pay the $50.00 from Cisco. Numerous cisco sles people and techs have tole me this, so I don't want to hear "use the Cisco VPN Client". I want to know the best way to setup the PPTP on these router to make them as secure as possible. My feeling is i've had to open up port 1723 and GRE on these routers and people can try all day long to get authenticated on the network, and I want to see if there is anything I can do to limit this risk.
