@jaredbusch This seems to work.
May i ask though, what is the point of having 2 WAN connections if unable to use them at the same time?

Failover.

Or other types of load balancing that don't split a single connection.

Or as I said, you have your load balancing misconfigured. You can easily load balance as long as all connections from a single internal IP always use the same connection when going to the same destination.

Ive changed teh Weight of CLink connection to 100 and left Comcast at 1.
This has mitigated the issue. The B Channel timeouts still happen in the logs but so infrequently that I nor any user has seen the 'waiting for TLS handshake' issue for hours now when browsing.

Are you using round robin for the load balancing?

[momurda]

Yes

[dbeato]

@momurda Okay, so you need to make sure to use "User Source and Destination IP Address binding" That is what I use on my Sonicwall.

Yep. On Ubiquiti you need to set the load-balance group to sticky. https://help.ubnt.com/hc/en-us/articles/205145990-EdgeRouter-Dual-WAN-Load-Balance-Feature I've done this at a number of places now, works great.

In the Watchguard, there is no User Source and Desination IP Address Binding option. There is a Sticky Connections option.
So i think in WG my best option is to force all connections to use CLink at the Policy level. Whats interesting about this setup you can do this for any firewall policy, regardless of your MultiWan settings. I havent enabled this, but it would look like below(this is a snip that i setup but didnt apply to WG):

@momurda Enable Sticky as below

It depends on what you want. Your stated goal was load balancing. The watchguard can do it if you set it up properly. You did not do it properly and had problems. This is not a surprise.

But that does not mean to then not use load balancing at all.

It mean go back and RTFM and set it up properly.

Conveniently, you do not even have to RTFM because @dbeato has posted the instructions for you.

.

Ive already set sticky connections in the Global MultiWan.
The override option for this policy cant be enabled.

[dbeato]

@momurda But did you increase the default timeout from 3 minutes to let's say 10 minutes or so?

[momurda]

@dbeato Yes, 10 minutes actually, some time this morning.
