I have 3 RB1100AHx4 routers (HQ office and 2 branch offices) connected by IP tunnels and IPSec.
I was transmitting data from the HQ to the branch offices over a cable line at a rate of 24Mbps.
I upgraded my cable service (they changed the MODEM).
Now I can send to one branch office at the rate of 44Mbps, but the other one is limited to 10Mbps.
I have tried comparing settings between the 3 routers, everything seems the same.
This started when I was on 6.47.3. When 6.47.4 was released, all routers were upgraded, but still the same results.
I tried changing from an IP tunnel to a GRE tunnel, but the same results.
I have done bandwidth tests at all 3 sites, and they have the results I expect.
The branch office with the issue has a 1G download rate.
What would set the bandwidth of the tunnel to 10Mbps?
What else can I test/look for to solve this?
