Port forward to VPN Client?

http://unix.stackexchange.com – I've run into a bit of a puzzle and haven't had much luck finding a solution. Right now I am (sadly) connected to the net via Verizon 3G. They filter all incoming traffic so it is impossible for me to open ports to accept connections. I currently have a linux virtual machine at linode.com, and the thought crossed my mind to install pptpd and attempt to do some iptables port forwarding. I have pptpd installed and my home machine connects happily. That said, here's some general info: Server (Debian) WAN IP: x.x.x.x on eth0 - pptpd IP: y.y.y.1 on ppp0 - Client VPN IP: y.y.y.100 To verify I was (HowTos)

Stories similar to Port forward to VPN Client?

Hello,

I've run into a bit of a puzzle and haven't had much luck finding a solution. Right now I am (sadly) connected to the net via Verizon 3G.

Hi,

I want to start a small pptpd server on a vps in the us so I can spoof the ip and get hulu and netflix us version etc. I have gone and set up the pptpds server works great.

My question is:

Since the vps comes with 5 ips, how can I allocate a specific ip to a pptpd client.

Situation is this: Client C connects to pptpd VPN server V. C is listening on port 80 (webserver). How should pptpd on V be configured so connecting to V:80 would actually connect to C:80? Server is running ubuntu 12.04 OS.

After issued command to stop pptpd, the pptpd won't stop until all the VPN client has disconnected. The following code shows pptpd is still running after issuing the stop command.

ubuntu@ip-10-138-31-87:~$ sudo /etc/init.d/pptpd stop Stopping PPTP: pptpd. ubuntu@ip-10-138-31-87:~$ ps -ef |grep pptpd root 5524 1 0 21:46 ?

I have some problems connecting a Playstation to my VPN via another PC.

Hardware: PC that should route incoming traffic from the Playstation to VPN: eth0 - connected to the internet eth1 - connected with my Playstation.

Hi all,

I apologise if this question has been asked a million times before.

I have an Ubuntu 9.10 server with the PPTP VPN server daemon installed (pptpd).

We've been struggling with some kind of network/routing issue with a PPTPD based VPN where the clients can't access certain internet domains/ips through the VPN.

I am using Ubuntu Server 11.10 64 bit

I am trying to get PPTPD VPN working on it

I have tried multiply installation guides but each one I still get the same problem

When a client (Me on my laptop) connects, the network on the server freezes

When I try to ping say 8.8.8.8(The Google public DNS server) it will run though multiple pings before there is no response back.

I need to reject all incoming packets in port 1723 and redirect all packets that incoming to port:xxxx to port:1723 in localhost.

I tried this rules but not works until i allow 1723 on INPUT chain of filter table.

# iptables -A INPUT -i eth0 -p tcp --dport xxxx -j ACCEPT # iptables -A PREROUTING -t nat -i eth0 -p tcp --dport xxxx -j REDIRECT --to-port 1723

after adding this rule it works fine:
