Hi Abhay singh3 : Thank you for contacting Sophos community team. As per provided setup details WAN Port2 and WAN Port3 both are in same subnet. It is not recommended to configure 2 same networks on 2 different Interfaces of XG and this may create a problem of ARP conflict due to which WAN will go up down frequently or one of them may remain in a down state only. However, if requirement is there to SNAT traffic of LAN 10.0.0.35/22 via 103.78.14.66 IP then you may add an alias on your existing WAN Interface with that IP and you may define customer SNAT policy via NAT rule for this LAN network which forward or NAT traffic via define IP only as per your configuration.
