Hi, i have several snap gear pptp server (vpn) boxes in diffrent companies that i have remote users connecting into.  the model is below.

lateley, some of the users using cable modems through adelphia (cable provider) have not been able to conenct to the pptp server on the device (the snapgear).  i was unable to resolve the issue until i moved the users to dsl, then all worked fine.  to aleviate the problem in the future i have decided to find out why.

question:  what ports does the pptp connection need/require?  maybee it depends on the security that i set from the begining, so i should have found out that and listed it here.

note, even on the cable users that cant connect to the more secure sites, i can connect to the above mentioned boxes that have lower security.  

-thanks, dan
