Re: [Poptop-server] Handing out Public IPs

Another problem might be that in many cases in server hosting companies (or the one who gives you the public ip) check MAC addresses and their changes, and automatically ban if something wierd happens like in this case different computers announce their MAC assigned to that IP too frequently. My solution was that every time ppp connects it runs a script. The important part of this script is: $IPTABLES -t nat -A PREROUTING -d $IP -j DNAT --to-destination=$ifconfig_pool_remote_ip $IPTABLES -t nat -A POSTROUTING -s $ifconfig_pool_remote_ip -j SNAT --to-source=$IP in which $IP is a public ip (assigned to eth0:n), $ifconfig_pool_remote_ip is the one that ppp gave as internal address. Hope this helps... Andras -----Original Message----- From: Charlie Brady [mailto:cha...@mi...] Sent: Monday, March 29, 2010 3:53 PM To: Evan LeStrange Cc: pop...@li...

It's very unusual IMO to distribute public IPs to the clients. PPTP is a VPN technology, and "PN" stands for "Private Networking". > Running ifconfig on the server results in the following: > > eth0 Link encap:Ethernet HWaddr 40:40:46:ff:6e:2d > inet addr:x73.x03.119.137 Bcast:x173.x03.119.255 > Mask:255.255.255.0 > inet6 addr: fe80::4240:46ff:feff:6e2d/64 Scope:Link > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > RX packets:1558864 errors:0 dropped:0 overruns:0 frame:0 > TX packets:1203789 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:1000 > RX bytes:925299168 (882.4 MiB) TX bytes:893886411 (852.4 MiB) > > eth0:1 Link encap:Ethernet HWaddr 40:40:46:ff:6e:2d > inet addr:x73.x03.119.166 Bcast:x173.x03.119.255 > Mask:255.255.255.0 > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > > eth0:2 Link encap:Ethernet HWaddr 40:40:46:ff:6e:2d > inet addr:x73.x03.119.167 Bcast:x173.x03.119.255 > Mask:255.255.255.0 > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 ... > I'm using the default pptp-config with: > > localip x73.x03.119.137 > remoteip x73.x03.119.166-167 Here you have x73.x03.119.166 and x73.x03.119.167 set up as local IP addresses on the server, and are also asking pptp to configure the remote clients with the same IP addresses. That is certain to interfere with routing. -- Charlie ---------------------------------------------------------------------------- -- Download Intel® Parallel Studio Eval Try the new software tools for yourself.
