Need asistance in the following situation:


192.168.10.x LAN1--------1-Endian2.4----------------IPSEC tunnel-------2-Endian2.4---------192.168.20.x LAN2

Goal: The two LANs have to see each other. Obvious firewall rules are necessary. Can someone assist in this topic?
I replaced 1-Endian with IPCOP and from LAN2 I can browse LAN1 (in outgoing firewall is necessary to add a rule to allow outgoing SMB traffic)
But no way to browse LAN2 from LAN1 (tried different DNAT rules but no luck)
Please advice if someone got this configuration working
