newbie here, trying to establish a IPSEC VPN to 3rd party Fortigate FW.
below are the logs from Fortigate as i cant find anything much from CP debug IKE.ELG log.
Phase 1 passes except Phase 2(refer to pic or below).
peer proposal is : peer:0:192.168.1.251-192.168.1.251:0, me:0:192.168.200.0-192.168.200.255:0
is the ip in red should be my lan 192.168.220.254 address to correct the issue?
tried many settings but still get there error. where should i config to get the correct peer proposal?
External: 192.168.1.251, LAN: 192.168.220.254
External: 192.168.0.253, LAN: 192.168.200.1
