v4 tunnel ports restrictions
« on: June 05, 2010, 10:04:47 AM »

The PPTP tunnel is now confirmed running reliably  :)  This in turn allows to raise a few new questions re the IPv4 service, can you clarify please :

- outgoing ports  : I did no extensive testing, however it appears at least TCP port 25 (SMTP) is blocked by the gateway. Is it intentional/necessary ? Other TCP/UDP ports similarly blocked ?

- ingoing : I've seen TCP 623/646/664 discarded ("stealthed") and 912 (VMware server management?) open time and again at your gateway. Not tested high ports. Can we freely run listeners on any other TCP port, else what TCP/UDP ports are reserved by HE ?

Thanks again

Me too. I was just going to reflect this. PPTP blocked some port. when I use PPTP VPN,then my server can't use local ISP ipv4 network. So mail server don't send any email.

To prevent abuse of services, possibly in other ways. If he is good service, I am willing to pay a little fee.
