Dialup Ipsec Vpn Tunnels

[safwan303]

We had multiple dialup ipsec vpn tunnels configured at our Fortigate 200E v5.4.1 and all are working fine but today we create a new Dialup ipsec vpn tunnel with the almost same parameters only interface ip and remote ip in phase 2 is change having range from 192.168.145.1-100 and local address in phase 2 is 0.0.0.0 , so only those client can send and receive traffic who have odd number IP like 192.168.145.1,192.168.145.3,192.168.145.5...... and so on but dialup users who were having even number ip like 192.168.145.2,192.168.145.4 and so on ,can only transmit data but unable to receive data where as old tunnels ranges are working fine .

How to fix this sudden behavior change in FG ?
