Policy Routing - Incorrect source route rule?

[Guest]

[DFen]

I have tried creating a policy route along the following lines:
Network->routing->policy routing

Source network/ip (Green):
192.168.1.201/32
192.168.1.202/32

Destination network/ip (Red):
...20
...30

Service: ANY
Protocol: IP
Route Via: uplink1


This appears to create enties in the mangle table: iptables -t mangle -L POLICYROUTING -nv

    0     0 CONNMARK   tcp  --  *      *       192.168.1.201      ...20       CONNMARK set 0x7c8/0x7f8
    0     0 RETURN     tcp  --  *      *       192.168.1.201      ...20       CONNMARK match !0x0/0x7f8
   0     0 CONNMARK   tcp  --  *      *       192.168.1.202      ...20       CONNMARK set 0x7c8/0x7f8
    0     0 RETURN     tcp  --  *      *       192.168.1.202      ...20       CONNMARK match !0x0/0x7f8

    0     0 CONNMARK   tcp  --  *      *       192.168.1.201      ...30       CONNMARK set 0x7c8/0x7f8
    0     0 RETURN     tcp  --  *      *       192.168.1.201      ...30       CONNMARK match !0x0/0x7f8
   0     0 CONNMARK   tcp  --  *      *       192.168.1.202      ...30       CONNMARK set 0x7c8/0x7f8
    0     0 RETURN     tcp  --  *      *       192.168.1.202      ...30       CONNMARK match !0x0/0x7f8

However in the source route rules table: ip ru sho

10:     from 192.168.1.201 lookup main


This appears to cause the later rule:
199:     from all fwmark 0x7c8/0x7f8 lookup uplink-uplink1
NOT to be reached for the first Source IP in the policy route, and traffic is routed via the default route in main.

This does not appear to be the correct action.
I need the traffic to be routed to an alternate gateway.
