Hello Tarhon-Onu,
TOV> Ideea la VPN este ca sa poti transporta pachete intre 2 retele

TOV> retea.
TOV> Nu este obligatoriu ca un VPN sa aiba ca si capete 2 retele

TOV> Ia da matale un tcpdump -i eth1 host 192.168.10.1, vezi, ce
TOV> zice? Zice datele in clar sau se fac transmisii de date doar pe proto
TOV> 50?
Scuze ca raspund asa tarziu, am fost plecat din localitate putin :)
Am dat tcpdump... si transmisiile de fac in clar. Acum nu stiu daca
e foarte relevant, am citit ca in anumite conditii tcpdump nu poate
arata traficul criptat. (versiune, distributie )
Era usor cred daca aveam interfata ipsec0, dar pe 2.6sec nu exista -
din cate am citit pe net - ca altfel puteam sa rutez traficul.
Maine, cand va fi cineva la munca in capatul celalalt, o sa-i pun sa
dea un ping, sa vedem daca merge de la ei spre mine.
ip route get 192.168.10.1 imi arata doar ca traficul se duce prin
gateway-ul de la connex - ceea ce e normal cred.
Aaa, si inca ceva, LAN-ul de la mine iese in net prin SNAT pe eth1,
credeti ca sut probleme din cauza asta?
Va dau mai jos si output-ul de la ipsec auto status:
000 interface eth0/eth0 192.168.0.1

000 interface eth1/eth1 81.12.xxx.xxx
