VPN Connectivity

Post by aburrow » Fri Jan 15, 2010 9:47 am

My current setup is.

2 x Macintosh Computers located behind a dlink ADSL router. I'd like to be able to connect via VPN from home to access files on at least 1 of these machines.

WHat I've done so far.

1. Allowed VPN passthrough on the dlink router to the IP address of Machine1.
2. Have setup EasyVPN on Machine1.
3. I cannot access Machine1 from home though.

Troubleshooting.

1. As a test I can attach to Machine1 from Machine2, so I believe the VPN side of things is good to go.
2. Tried a tracert from home but I get no response from the static IP that Exetel have assigned my router.

What am I doing wrong?

Thanks

The tracert will probably timeout on the static IP hop because modems by default are configured to not respond to pings. You can look for a setting like "Enable ICMP pings" on the modem and this will help for ping/tracert tests but otherwise it is not necessary.

There are no blocked ports on Exetel's network, so this will not be the cause

When you say you allowed VPN passthrough, this was an option on the DLink, or did you forward a particular port to the IP address of machine 1?

You could also just look at the simpler Personal File Sharing built into the Mac and then just access files via FTP (see http://www.macworld.com/article/132002/ ... c2503.html and forward port 548 for Personal File Sharing or 21 for FTP) or look at Apple Remote Desktop as well I guess

I think this is likely to be part of the issue.

VPN Passthrough is really designed for allowing machines on your network to connect to VPN's elsewhere, not the other way round. You may need to set up appropriate port forwarding to the VPN working.

I think you may need to port forward 1723 to machine1 (for VPN passthrough via PPTP). For L2TP VPN connections, you need to open UDP port 500 for Internet Key Exchange (IKE) traffic and UDP port 1701 for L2TP traffic
