UAG 5100 how to optimize the two Wan available?
Freshman Member
Dear Sir ,i have a UAG 5100 with two wan connexions Wan1 20M/20M and Wan2 15M/ 15M ,usually i use them so but in failover purpose,but not i see that the Lan consumption have increase mor emore because new streaming web and others.
Now i face bandwitch saturation in Lan ,how can i use the second wan2 bandwitch to have 35M/35M avaible for my Lan?
best regards

Hi @greg,
With Load Balancing Algorithm setting, assume both wan interface are active mode, it can balance the traffic load between two wan interface. The device overall bandwidth to Internet can reach 35/35M. Just confirm if both wan interface are active mode.

- Backup your lastgood.conf and startup-config.conf files before start to edit anything.
- Go into trunk section of interfaces (Screenshot coming from USG60, Firmware 4.71 but concepts should be similar.
In this image you should find something similar to your UAG 5100. The device is using default trunk or one of the user configurations.
You can create a "newer" user configuration an pick the preferred one.
Whick one, among wrr or llf? Pick your UAG 5100 manual, section 11. Should explain to you what to prefer, and why.
When created, you can pick it clicking on the dropdown.
Under User Configuration you will find the system_default_wan_trunk. I strongly suggest you, if present or selected, to not edit it. It will be a easier fallback.
Consider that you either setting, is quite unlikely to reach 35MB into a single connection (device might happen, but still unlikely. I'm not aware of any service that can serve via multipoint connection the same client.Anyway, some of the traffic could be routed to WAN2, but unless tweaking manually the source routing, you'll have no control of which connection will be used for one host and when it will be switched to the other one. You can pick the algorithm and the weight, then let the device "do its thing", even if you don't understand why and how it picked one or the other route.WANs configuration about connectivity check and Ingress/Egress will play a consistent part of interface behavior. Also Bandwidth Management (BWM).If the current configuration satisfy well enough needs, keep it available when you'll need it. As a rule of thumb... change something. Take notes. Let it fail, analyze stats, rethink. Change again. Take notes. Let it fail (hopeful less).Take time to understand how the thing work before doing config stunts.5 -
Thanks sir,but I have not understand what to do exactly step by step.?I have last firmware0

Hi @greg,
The device overall bandwidth can reach 35/35M. but it's not something like aggregation for wan 1 and wan 2 bandwidth. We would suggest enlarge Internet speed if overall bandwidth is full loading.0 -
ok wchich configuration to do so The device overall bandwidth can reach 35/35M in case?please help
