Hello,

Not sure if anyone here know about corporate implementation, but anyway, here goes.

We have subscribed to the UNIFI BIZ 20 package at our office. The UNIFI for my office is the highrise building type of implementation. All the fiber termination is done at the building MDF room. Then copper wire is being run up to the datacenter floor via CAT3 cables.

From my end, i have replaced the DLINK router with a Cisco ASA 5512X, which is connected to the Huawei Echolife. The cisco asa has 3 zone configured, outside, inside and dmz.

Now my issue is, i can get very good download speed, more than 20Mbit/s, but upload speed for some reason does not exceed 7Mbit/s with the Cisco ASA. The ASA cannot managed to get a PPPoE connection establish if i plug it into port 1 of the Huawei Echolife, port 2 to 4 works fine.

When i unplug the ASA and put back the DLINK router, i can get 20Mbit/s for both download and upload. It can only managed to get a PPPoE connection on port 1 of the Huawei Echolife. If i plug it to port 2 to 4, no PPPoE connection is establish.

I have also logged into the Huawei Echolife box, and the box WAN connection does say 20Mbit/20Mbit for the PPPoE speed negotiated. So that pretty much rule out TMNET wrong capping, and the test with the DLINK router also confirmed it is not a line issue.

I have been troubleshooting this for about a week and have not come close to any solution. Does anyone here have done any corporate implementation for UNIFI with a Cisco ASA?
