Major oops...!!!!

To any that saw my post on the homephone forum in thread started by wjsd7 and wondering what I was on, here is an explanation as to why I took it down.

Firstly Don't post with less than 2 hours sleep 🙂

It is basic but complicated if you are not used to medalling with routers and settings etc. If you are not, best leave it all alone.

Basically, I was thinking more corporate routers than home routers so much of what I said was immaterial. I have just done 1500 hours of update studies in a few months for my systems/networking studies to take in VOIP. God knows why really as I am 67 and retired and never going to work in it again!! Obviously NAT is on with both routers as my (I don't believe the TP-Links can either) second cannot run in pure router mode. Therefore you only need a static routing on the Hub 3 set to IP of second router. Second router Nat handles all traffic to Hub 3, so a second static route is not needed nor would work.

The reason for the second router on a different domain is further security. In my own case using an ATA into lan port, (as internal phone port had failed) the Hub 3 played up and there was a need to drop the router to a less aggressive state. Meaning less secure, hence a different domain. I have trading computers which for obvious reasons you can see why I don't want a weakened firewall in front of them.

You cannot make the necessary adjustments to either firewall in my case the Hub 3 and Linksys MR5500 as neither allow it. Therefore all devices were installed on the lan of the second router. This way all devices talk to each-other on second router. In a weakened state I would NOT connect any devices to the Hub 3 anyway.

Effectively no device can access the second router lan. NOT even with short cuts. I know I originally posted using short cuts but I was assuming very wrongly that firewalls could be modified and the user had the expertise to set new rules effectively and securely, but as I said none of the mentioned routers allow that type of modification to the firewalls. And why would you with a weakened firewall.

So, I killed the post as it would cause more problems than fixing. Yes Hub3 worked with VOIP on ATA through lan and transferred connection to the Linksys in my case but the Hub 3 basically failed big time, crashing multiple times for what reason I have no idea! So I removed it. I would not use this setup if you are using an ATA only if your telephone port is working on your hub. The Hub 3 router does not like ATA's.

It will all work if you want the VOIP on but still use your own router using Hub3 as main router feeding second router with static route set on hub 3 pointing to second router IP. Whether you split domains is up to how you want it all to work.

If you are not splitting domains then you would not adopt this method anyway.

So sorry for anyone that this caused confusion to them.

Though for 99% of home users the Hub 3 will do the job required of it.
