u nastavení MK2 máš špatně to poslední pravidlo (accept v NATu). Ale je možný, že to je jen chyba CTRL+C a CTRL+V :

My máme de fakto stejnou konfiguraci, jen máme v peeru zaškrtnuto i NAT Traversal, což u Tebe nevidím.

pls myslis toto prehodit dst addres a dst addres...

MK2

/ip firewall nat

add chain=srcnat action=accept place-before=0 \

src-address=192.168.2.0/24 dst-address=192.168.144.146.0/24

po uprave

/ip firewall nat

add chain=srcnat action=accept place-before=0 \

src-address=192.168.144.146.0/24 dst-address=192.168.2.0/24

Zkousel jsem i nat travesal ale bez nejakeho uspechu... pls ma to tak byt.... dik za info

ano, ten NAT uz mas spravne. A taky bacha na to, ze pokud to mas spojeno jen IPsecem, mezi tema routerama si nedopingas! Tzn, vyzkousej pingat z nejakyho PC v LAN1 na jiny PC v LAN2.

fidosoft

no to je ale blbustka. skusim to a dam vedet dikec...

fidosoft

Tak bud jsem dlbe cetl nebo jsem uplny trotl ale ani ve snu mne nenapadlo ze ping z MK1 nebo MK2 nepojede i kdyz bylo navazane spojeni ...

Po pingu z pc 1 spojeni navazano /ip ipsec remote-peers print "state=established" a /ip ipsec installed-sa print detail "state=mature" ... takze moc dik

pro informaci pro ostatny fungujici nastaveni MK1 A MK2 Povoleni 4500 udp neni nutna aspon ne u naseho spojeni
