I have a pptp server which issues a local IP to each user on successful auth. These IP's are in the range of 10.1.1.2-10.1.1.254.
This all works ok, however I then have a set of 128 public IP's that I want to use with those so that when they are seen on the Internet they have a different public IP (or at least 1 public per 2 private IP's).
I have not got MASQUERADE in the IPTables as this would defeat my point, so I added some POSTROUTING to assign the IP's, but this is not working, can you give me a heads up as to why?
This is my Routing in IPTABLES:
iptables -t nat -A POSTROUTING -s 10.1.1.2 -o enp2s0f0 -j SNAT --to-source 111.222.62.131
iptables -t nat -A POSTROUTING -s 10.1.1.3 -o enp2s0f0 -j SNAT --to-source 111.222.62.131
iptables -t nat -A POSTROUTING -s 10.1.1.4 -o enp2s0f0 -j SNAT --to-source 111.222.62.132
iptables -t nat -A POSTROUTING -s 10.1.1.5 -o enp2s0f0 -j SNAT --to-source 111.222.62.132
As you can see, I am sharing the public IP's in pairs with the private IP's. The problem is that some are connecting OK to the pptp server but not routing onto the internet whilst others connect and can route fine.
Here is the output from iptables -t nat -L -v -n:
Chain PREROUTING (policy ACCEPT 1152K packets, 91M bytes)
pkts bytes target prot opt in out source destination
Chain INPUT (policy ACCEPT 350K packets, 22M bytes)

Best Answer
As I can see now, from your detailed update, most likely it seems that you don't have those IP's assigned on your local network interface. You've only added 111.222.62.130 on your server. In order for linux S(ource)NAT to work, you must have every IP address you're NAT'ing to (--to-source) to be actually added on your network interface.
Check
ip address helpon how to assign additional IPs to an interface. You must issueip address add 111.222.62.X dev enp2s0f0for every IP you want to have SNAT working for. It will be convenient to write a script to fill those values.Be aware, that once you'll add those IPs on your local interface, you will "expose" your server via them to the Internet. You might use iptables INPUT table to block unwanted local connections to those IPs. By local I mean only to your server. Those coming through NAT are subject to FORWARD table only.
PS: If that it's not the case, also please check and post your
ip addr ls.
