Re: slow connection into 4321

Hulk8647 · ‎04-10-2018

Trying to figure out why my connection from the ISR4321 is sooo slow. I tested first with plugging my laptop directly into the modem. From the modem directly, I'm hitting speed of up to mid to high 90's. When I plug my 4321 into the modem and use the 2nd interface to the laptop, I go down to mid or high 18's. How can I go from 90's to 18's? I posted my config. License should push 50 in and 50 out. No idea what is causing this. My g0/0/0 is inside and g0/0/1 outside. Any help?

reduce the MTU and TCP mss under the tunnel interface,
with 40 bytes
and check again with DMVPN.
