Dear PAT,

Remote-Access Vpn is the right solution for you.
You may buy a Cisco ASA or a router for that.
I work for a cisco partner and could certainly help you out in purchasing. visit the url to know more.

Hi, thank you for the list of ports. May I ask which windows’ services need to be enabled to be able to use VPN? You see, I have some services disabled for performance reasons. Any adviced would greatly be appriciated. Thanks.

Question, I am trying to give an employee working access to our network from her home office. Is a VPN the solution for me. And if so, where do I start.

Thanks for your help.

[...] enable port forwarding on your router depending on the protocol you used (default is PPTP), over these ports. Then create a new outgoing VPN connection on their PC that points to your IP address, and voila. [...]

According to Wikipedia, PPTP uses both TCP and UDP… I’m not sure if L2TP does the same.
Here’s my ACL to allow VPN traffic (somewhat relaxed):

permit tcp any 10.6.14.0 0.0.0.255 gt 1023 established
permit tcp 10.6.14.0 0.0.0.255 any eq 1701
permit udp any any eq 1701
permit tcp 10.6.14.0 0.0.0.255 any eq 1723
permit udp any any eq 1723
permit udp any any eq 500

It is assumed that internal network is 10.6.14.0/24.

It’s hard to remember all the ports! I’ve made this list a favourite!
