Hi. I was wondering if you could help, please.

I have everything set up pretty much as I would like it, with both a private network and an isolated primary guest network. In addition to the 2 wireless networks broadcasted by my DDWRT Router, I also have a Netgear Powerline [PLW1000] extended wireless network [plugged into my DDWRT with LAN] for guests at the far end of the property who are not in range to access the primary guest network.

The only change I would like is to ensure that the secondary guest network, transmitted wirelessly from the Netgear Powerline, is isolated from all other networks. At the moment, the secondary guest network seems to be bridged to my private network.

I'd be grateful for any help. This is my first post, so please go easy on me! Thanks.

You weren't very clear about this "isolated primary guest network" as to whether that's wired, wireless, or both. Typically it would be wireless by creating a VAP specifically for guests. Any other remote network (regardless of the specifics of its infrastructure, e.g. powerline) can connect to that VAP using a wireless client device (e.g., wireless ethernet bridge). It's no different than any other wireless client that connects to the guest VAP.

Thanks so much for looking at this eibgrad and sorry that I wasn't more specific.
Both the 'private network=A' and 'isolated primary guest network=B' are wireless. The third wireless network (C), for further away guests, is broadcasted by the Wireless Powerline, which is plugged into the router with a LAN. I would like C to be isolated in the same way that B is, but can't work out how to do it.

Does that make sense? Thanks.

Separate a LAN port on the switch into it's own VLAN.

As your router is Broadcom, you have to post in that forum. We cannot give you a generic answer for this chip-set dependant question.
