i tried pppd ....options.... 10.255.246.1:10.255.246.100 and pppd on other side because 10.255.246.* is mine ethernet subnet this pppd connects fine and then doesn't work. no ping!!! with any other address line 10.1.1.1 (not in ethernet subnet) all works fine. proxyarp doesn't fix. is it bug or i did something wrong?
