I've been trying to get this IPSec VPN setup successfully for a while now, but it just got moved up on the priority list. Here is what I have:
Main Office
EdgeRouterPoE - Firmware v1.9.0
WAN1 - Cable Internet - Shown in configs as 68.123.123.210 (not real IP)
WAN2 - DSL set as Failover
Local Network 192.168.25.0/24
Remote Office
EdgeRouterPoE - Firmware v1.9.0
WAN1 - Cable Internet - DHCP with DynDNS host - shown in configs as remote-office.dyndns.org (not real)
Local Network 192.168.15.0/24
After reading through many posts and adjusting settings, I've gotten to the point where from the Main Office, I can access devices at the remote office, but not the other way around (which is ultimatly what we need).
Here are the configs:
Edits made for security:
Public IPs Changed throughout the configs
Dyndns hostname changed
Main Office Config:
