i have some question about network topology:
We have a Cisco ASA Firewall with site-to-site VPN IPsec with remote Pix Firewall.
Last year we implemented a Peplink Balance in Drop-in-Mode. So Peplink has Public IP, and its internal LAN is a Public LAN (4 public IPs) and NAT-ed LAN 192.168.1.0/24 is behind ASA Firewall.
Now we need to establish a new VPN IPsec Site-to-site with a remote Fortigate (LAN B 192.168.2.0/24) and our Peplink device.
Is that configuration supported?
Current (not working) configuration:
Peplink Balance Device
IPsec VPN --> established
NAT-T --> Enabled
LAN --> 18.104.22.168/29
IP --> 22.214.171.124/29
IPSEC VPN --> from 192.168.1.0/24 to 192.168.2.0/24 (established)
Exempt NAT 192.168.1.0/24 --> 192.168.2.0/24
default route 192.168.2.0/24 to 126.96.36.199/29 (peplink device)
Thanks in advance
