В iptables proписываю но не проходят. Есть мысль (из описания vpn) ЧТО маршрутизация в нем не ядром линукса обеспечивается ю, а самим softethervpn ом. И надо еще в нем пробросить, но я не знаю до такой степени тонкости маршрутизации.
Т.е. мне необходимо при обращении по ipservera:порт попасть на машинусерыйip:порт
