IPsec VPN Tunnel backup
Hi,
I would like to ask for help. I have IPsec site to site VPN tunnel between HQ and office. At both ends I have ER605 (R605). Because of lacks of internet connections I would like to setup "backup" tunnels. At both ends I have second ISP. I connect it through WAN/LAN Port 2, so both routers have 2 internet connections. But When I try to setup new IPsec VPN tunnel, it is not possible. I cannot create VPN tunnels with same IP addresses at ends. HQ is 192.168.1.0/24 and office is 192.168.2.0/24. How can I solve this ? ( If next device is needed, it is no problem. I use WD9980 and WD9960 for wifi and they also can create VPN tunnels... )
Many thank for Your helps.
