Hi, this is how is configured a RB750:

ip address
4 ***.***.***.130/28 ***.***.***.128 ***.***.***.143 ether5_WAN
5 ***.***.***.131/28 ***.***.***.128 ***.***.***.143 ether5_WAN
6 ***.***.***.140/28 ***.***.***.128 ***.***.***.143 ether5_WAN
7 192.168.1.10/24 192.168.1.0 192.168.1.255 ether3_LAN

ip firewall nat
1 chain=srcnat action=masquerade out-interface=ether5_WAN
2 chain=srcnat action=src-nat to-addresses=***.***.***.140 src-address=192.168.1.250
3 chain=dstnat action=dst-nat to-addresses=192.168.1.250 dst-address=***.***.***.140

The rule #3 is working well, when i try to connect to the public ip ***.***.***.140, services on 192.168.1.250 answer correctly, but when i check the outgoing public ip it tells me ***.***.***.130 instead of the .140, so the #2 rule doesn't seem to work.

How can i do? is there something wrong in the rule #2? Thanks

it is hard to understand your configuration and your targets

Not sure I am reading it right, but your 1:1 rules need to be above your masq rules in the firewall->Nat
