The Baicells UE has a 1500 MTU as its default. Older versions of the Telrad firmware did not support 1500, but I was told the newest versions will. New versions needed for eNB, EPC, and UE to support 1500MTU.
One of our customers is having an issue with his VPN. On the UBNT 5Ghz network he had no issue. Now that he is on the LTE he is unable to establish a VPN connection. Adair thinks it is packet fragmentation since its at 1400MTU.
