    Hello Rakesh,

    Depends on how you have set your Traffic selector configured. 

    If your traffic selector is set with the IP's or subnet of the mentioned IP's then you would just need to make sure the policies are in place. 

    If not you would have to setup a traffic selector to to allow the traffic to pass through ( and policies should allow them too ) 

    example:

    set security ipsec vpn VPN_NAME traffic-selector TS1 local-ip 10.231.157.0/24 << modify the subnet accordingly. 
    set security ipsec vpn VPN_NAME traffic-selector TS1 remote-ip <>

    Make sure the peer also have same traffic selector configured. 

    Regards,

    Hello Rakesh,

    The config should like below:

    set security ipsec vpn VPN_NAME traffic-selector TS1 local-ip 10.231.157.a/32
    set security ipsec vpn VPN_NAME traffic-selector TS1 remote-ip x.x.x.x/y
    set security ipsec vpn VPN_NAME traffic-selector TS2 local-ip 10.231.157.b/32
    set security ipsec vpn VPN_NAME traffic-selector TS3 remote-ip x.x.x.x/y
    set security ipsec vpn VPN_NAME traffic-selector TS4 local-ip 10.231.157.c/32
    set security ipsec vpn VPN_NAME traffic-selector TS4 remote-ip x.x.x.x/y
    set security ipsec vpn VPN_NAME traffic-selector TS5 local-ip 10.231.157.d/32
    set security ipsec vpn VPN_NAME traffic-selector TS5 remote-ip x.x.x.x/y
    set security ipsec vpn VPN_NAME traffic-selector TS6 local-ip 10.231.157.e/32
    set security ipsec vpn VPN_NAME traffic-selector TS6 remote-ip x.x.x.x/y
    set security ipsec vpn VPN_NAME traffic-selector TS7 local-ip 10.231.157.f/32
    set security ipsec vpn VPN_NAME traffic-selector TS7 remote-ip x.x.x.x/y
     

    Also, as said earlier, it would need similar / equivalent config on the peer end. 

    Regards,
