I had to set up a long wireless link on short notice and didn't have the time I would have liked to research things. Did what I could, got the link up, and hoped to fix things later.
Long story short, I have 4 wireless devices the make up the link that are before my RB750 router (on the WAN side) that I need access to. They are on the same subnet that the router serves (192.168.0.x).
Doing some research after the fact, I have learned that having them on the same subnet is bad. Would be better if they were on, say 192.168.1.x. I can change that, but it's difficult - requiring a visit to the remote site.
I have also read some past posts on things like this:

I already had the masquerade rule mentioned in Firewall>>NAT:
add action=masquerade chain=srcnat disabled=no out-interface=ether1-gateway
but no access.
Is it possible to make this work, or do I need to change the IP's of the 4 wireless link devices?
The last post of the thread says this:

Resolved, my steps:
1. Assign IP to the ether1-gateway interface in the same range as the ADSL modem, but different to the LAN (this is the step I missed)
2. Create a Masquerade NAT rule for the ether1-gateway interface.

Don't know if this will work, and didn't want to kill the remote network trying it. I get the impression that since the link devices are on the same subnet that it won't. If I'm wrong, please let me know and what steps I need to take to get this working.
Thanks for any help and advice on this.
