Question About Static Route and SD-WAN Policy Route

Question

Hi All, 
 I am having trouble with routing. I will try to explain what i need. 
 If traffic initiated from XG2 MPLS interface to XG1, XG1 will reply from MPLS interface. 
 If traffic initiated from XG2 XFRM1 interface to XG1, XG1 will reply from XFRM1 interface. 
 I have configured with following configuration but regardless of the interface that initiates the traffic on XG2, XG1 send reply packet from MPLS interface. 
 Could you please help?

XG1 v18.0.4 MR4

XG2 v18.0.4 MR4

Port1(LAN):192.168.1.0/24

Port1(LAN):192.168.2.0/24

Port2(WAN):1.1.1.1

Port2(WAN):2.2.2.2

XFRM1 on Port2: 172.16.1.2/24

XFRM1 on Port2: 172.16.1.1/24

Port3(MPLS):192.168.30.254/24 Gateway:192.168.30.1

Port3(MPLS):192.168.60.2/24 Gateway:192.168.60.1

Static Routes: 
 Route1 
 Dest:192.168.2.0/24 
 Gateway:192.168.30.1 
 Interface:Port3 (up) 
 Distance:0 
 
 Route2 
 Dest:192.168.2.0/24 
 Gateway:172.16.1.1 
 Interface:XFRM1 (up) 
 Distance:1

Hi Yemliha Ipek , 
 Thank you for reaching out to Sophos Community. 
 The distance value is used to select the best path when there are two or more routes to the same destination. Route with a low distance value will be selected as the best path. 
 As per the current configuration, Route1 will be selected as the best path as it has a distance value lower than Route2. 
 If you change the distance value as below, then the traffic to 192.168.2.0/24 network at XG1 end will be routed via xfrm interface. 
 Route1 distance value: 1 Route2 distance value: 0
