set policy route tproxy rule 100 mark '2'
set policy route tproxy rule 100 set table '200'

then check the ip rule result .

vyos@r14# sudo nft list table ip vyos_mangle
table ip vyos_mangle {
	chain VYOS_PBR_PREROUTING {
		type filter hook prerouting priority mangle; policy accept;
		iifname "eth1" counter packets 0 bytes 0 jump VYOS_PBR_UD_tproxy
	}

	chain VYOS_PBR_POSTROUTING {
		type filter hook postrouting priority mangle; policy accept;
	}

	chain VYOS_PBR_UD_tproxy {
		meta mark 0x00000002 counter packets 0 bytes 0 meta mark set 0x7fffff37 return comment "ipv4-route-tproxy-100"
	}
}

All match marks 2 set mark 0x7fffff37 and used in the table 200

vyos@r14# ip rule
0:	from all lookup local
200:	from all fwmark 0x7fffff37 lookup 200
32766:	from all lookup main
32767:	from all lookup default

What is wrong here?

sorry , I thought the function should be "match mark 2 and use route table 200" , there is some misunderstanding , but if I only want route based on the mark ,not to change it , how to do it ?

btw , could we add a feature to support tproxy when do pbr ?
