IPSec VPN for Site to Site connection via dialup interface to Cisco Router

Hi All

I have problem with IPSec VPN for Site to Site connection via dialup interface.

Central Site (CS) LAN  CS Internet WAN –

Phase1-PSK Dialup to Remote1 – Phase2 CS LAN + Remote1 LAN

Phase1- PSK Dialup to Remote2 – Phase2 CS LAN + Remote2 LAN

Peer ID and PSK set in user group

UserGroup1 Remote1Users contains UserID of Remote1 and Password PSK1

UserGroup2 Remote2Users contains UserID of Remote2 and Password PSK2


Remote 1 – WAN Local ID Remote1


Remote 2 – WAN Local ID Remote2


The problem I see is when Remote2 calls in. The Fortinet is showing it as Remote1 and failing phase1.

When only a single VPN is configured that VPN works fine.

Any idea’s anyone?
