IP=$(/sbin/ip -o -4 addr list eth0 | awk '{print $4}' | cut -d/ -f1)

/sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

• I chose 10.10.23.0/24 arbitrarily, you can choose what ever cidr you want.
• I added debug to pptpd config and pppd config for make great log files.
• +mschap-v2 is non default and required for windows 10.
• change user and password in chap-secrets to something secure.

Setup the pptp connection on the windows server:

Note that setting "nodefaultroute" in the pppd options file has no effect as the windows client controls this. Change the settings on the connection adpater's properties. uncheck "Use default gateway on remote network"

once the link is up add a route to eve manually. run cmd as admin and do this:

netstat -rn

Look for the interface id of you ppp connection, then use the route add command here:

route add 87.237.34.200 mask 255.255.255.255 0.0.0.0 IF XX

87.237.34.200 tranquility.servers.eveonline.com
