Когато има проблем с мту-то (поне в случаите които съм виждал) се проявява след конекцията, слага се едно правило iptables и се решава проблема, но ти изобщо не се закачаш, според мен, нещо от сървъра те рита, за това ти казах и да провериш хв адреса (виждал съм една и съща мрежова карта с различен мак адрес под линукс и виндовс)
Ако искаш пробвай с това правило преди да вдигнеш тунела, но едва ли:

Код:

iptables -I FORWARD -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu

btw По-правилно е да се изпълни в mangle веригата.

Не става с правилата в таблицата.
Ето малко сниф с wireshark

И така нататъка връзката се осъществява

Някой ако му разбира на тази боза да свирка какво съм омазал в настройките
едит:
Да неби сървера да не иска да работи с толкова високи портове на които ми излиза трафика.

[10101]

Не се заблуждавайте, MAC - адресите нямат нищо общо.
 
Според мен е NAT, дано не се окажа прав.

[victim70]

Вероятно е нат но и под вин е същият нат. Проблема е че нямам контрол на връзката за да видя какво не му харесва.
Сисадмина е хипер претоварен наистина. Няма време да обърне внимание а и не искам да го тормозя с 'дреболии'.

ЕДИТ:
Писах в поста на пптп - да видим.
