Здравейте,
От доста време се опитвам да разреша един (предполагам елементарен) проблем
свързан с VPN и Ipchains.
Преди да напиша какъв точно е проблема искам да подчертая, че машината която
ползвам е много стара с Debian, Kernel 2.2.19 и няма никакъв проблем с VPN
връзките при ползване на реални адреси.
Въпросната машина се ползва като рутер с два интерфейса (единия с реален
адрес, а другия ползва служебен - "фалшив" такъв)
Ето и проблема:
немога да направя VPN връзка от компютър със служебен (фалишив)IP адрес,
който е маскиран на рутера с помощта на Ipchains (ipchans -I forward -i eth1
-s 192.168.0.3 -j MASQ).
