Hi Kurt, first of all, thank you for the very fast response!
No, the peplink is the only router / firewall on my network (192.168.1.1) - behind it, I have a Win2K8 server (with firewall disabled) on 192.168.1.4 - all on subnet 255.255.255.0.
I only have 1 incoming firewall rule to allow SSH (on a high port), and outgoing = Allow All.
I also tried (after I posted this question) by creating 2 incoming firewall rules, one for port 1723 and one for IP 47 but this also didn’t help.
I connect using a Mac on OSX 10.7.4 - connecting to the PPTP is painless and can access the admin page of the Peplink but nothing more…
Now here’s one question - my local LAN (where I connect to the internet) has the same subnet as the remote LAN (192.168.1.x) - could it be that the system is lost in translation? I have set the ‘send all traffic over VPN’ option so I thought that solved it - but could that be the issue? If that is the issue, I can’t change the local subnet (no access to the router) but could do it for the remote site, just wondering what the impact would be - I think the Win2K8 won’t like it if I suddenly change the subnet and probably, since I don’t have access to it from my current location, I think I won’t be able to access it anymore…
If you want me to test anything else, please let me know.
Thanks!
Bernard
