I am using a RB411UAHR running ROS v5.22 with an Sierra Wireless 7710 LTE mini-pcie card. The LTE works ok (31mbit/s download bandwidth), but when i activate the transparent proxy on the ROS without caching and redirecting all the port 80 traffic to the proxy, i can only get 1.8mbit/s download bandwidth on the clients PCs. If i upgrade the routeros to version 6.0RC5 and setup the same scenario that i mentioned before, i get 5mbit/s download bandwidth instead of the 1.8mbit from version 5.22.
The strange thing is that if i use an internet access through the ethernet instead of LTE interface and redirect all the port 80 traffic to the proxy i get the full bandwidth without limitations (around 31mbit/s on download), so the problem is not the ros web proxy, but the combination with the proxy with the LTE.
I don't know what else to do, so any help would be appreciated.
