I am trying to put in the line "fixup protocol pptp 1723" on our firewall. I tried this command line and got an error "bad protocol pptp". I also tried going through the graphic interface and there was not a PPTP available under the Fixup section.
We are running a PIX 506E using Cisco PIX Firewall Version 6.1(2)and Cisco PIX Device Manager Version 1.1(2).
I need to get this firewall to allow a non-static internal computer to connection through the firewall to an external VPN server. Currently it hangs at the validation stage. A specialist told me that I needed to add the fixup line above to get it to work but I cannot add the line.
Upgrade to 6.3(5) and you should be good to go. Note that this command will do what you want assuming that your internal user is VPN'ing out with PPTP. If he's using IPsec VPN then this command will not do anything for you.
