Hello, can you explain a little bit better your configuration and what you actually want?

Which port is closed where?

You said you were able to connect from your laptop, so what's the problem then?

Regards

I still do not understand what you want to do, but anyway try allowing the port 81 on INPUT chain for all interfaces:

iptables -A INPUT -p tcp -m tcp --dport 81 -j ACCEPT

Where that "program" is running? On the pptpd server or on your PC?

Does that program should be listening at port 81/3460?

BTW, you must explain the situation better if you want to get any help.

yes
no thing else

Ok, the things are much more clear now.

What you need is the so-called destination NAT iptables rule.

Before I provide you with that, please paste here the part of /etc/pptpd.conf where the localip and remoteip are specified.

!! hack-back !! · 04-18-2013, 05:06 PM

localip x.173.180.202
remoteip x.4.252.69
