I have had poor performance (constant zoom dropouts) while working from home using ATT’s modem. I was able to bypass ATT’s modem on my fiber connection and wanted to document up the hardware and software needed.

Hardware:

UDM PRO

Gtek GBIC Transceiver

Software:

https://github.com/pbrah/eap_proxy-udmpro

Process:

• Setup your UDM behind the ATT modem and get it online using (att’s fake) ip passthrough.
  • cat5 ont->att modem (ont port)
  • cat5 att modem (lan port 1)->udm port 9
• enable SSH on the UDM under SSH AUTHENTICATION menu item
• following https://github.com/pbrah/eap_proxy-udmpro instructions run the following commands
  • ssh into UDM
  • docker pull pbrah/eap_proxy-udmpro:v1.1
• change wiring to:
  • cat5 ont-> udm port 9
  • cat5 udm port 10 -> Gtek GBIC Transceiver -> att modem (ont port)
• ssh into UDM
  • podman run –privileged –network=host –name=eap_proxy-udmpro –log-driver=k8s-file –restart always -d -ti pbrah/eap_proxy-udmpro:v1.1 –update-mongodb –ping-gateway –ignore-when-wan-up –ignore-start –ignore-logoff –set-mac eth8 eth9

Notes:

• It takes a few minutes to settle you can watch the log to verify
  • docker logs -f eap_proxy-udmpro
• The modem will alternate blinking green and blinking red on the broadband led. This seems to be normal and does not inhibit the UDM from working as expected.
