Allowing ICA connecting to IC2 public cloud

I’M TROUBLESHOOTING SEVERAL ISSUES WHERE THE:

  • IC2 ICONS ARE MISSING ON THE PEPLINK 48P & 24P SWITCHES.
  • IC2 REMOTE ACCESS TO THE SWITCHES IS HINDERED DUE TO SLOW THROUGHPUT (ALL OTHER INTERNET CONNECTION SPEEDS ARE FINE).
  • 5 VLANS ARE NOT POPULATING CORRECTLY ON SWITCHES.
  • THE APO-AX & APO-AX-LITE UNITS ARE INTERMITENT, EVERY 2 MINUTES THEY STOP REPORTING TO IC2
    - WIRELESS CLIENTS CONNECTING TO THE AP UNITS LOSE WIFI CONNECTIONS EVERY 2 MINUTES.

BOTH SWITCHES ARE CONNECTED TO PEPLINK ROUTER 310X-5GH.
(WE REPLICATED THIS ISSUE ON TWO BR1 Pro 5G ROUTERS.)

  • THE ISSUE IS ONLY PRESENT WHEN WE USE THE CLIENT PROVIDED ATT CELLULAR CONNECTION.
  • ON OUR BENCH THERE ARE NO ISSUES WITH OUR DSL CONNECTION OR OUR ATT TEST SIM CARD
  • IC2 “DEVICE CONFIGURATION” IS DISABLED.

I’VE READ SEVERAL RELATED FORUM POSTS DATING BACK TO 2014 WHERE THEY MENTION THE FOLLOWING = Outbound PORTS USED ARE UDP 5246 & TCP 443.

QUESTION:

  1. I ASSUME THIS 2014 INFO IS NO LONGER ACCURATE?
    AS I ADDED 2 FIREWALL RULES TO BLOCK PORTS Udp 5246 & Tcp 443 AND THIS DOES NOT BREAK IC2 CONNECTIVITY TO THE SWITCHES ON OUR BENCH.

ARE PORTS NO LONGER BEING USED? INSTEAD, THE IC2 CONNECTIVITY ONLY USES “DOMAINS”?
ra.peplink.com
download.peplink.com
api.ic.peplink.com
push.ic.peplink.com

(I HAVENT HAD A CHANCE TO BLOCK THESE DOMAINS YET AND TEST).

ANY COMMUNITY AND PEPLINK ENGINEER INPUT IS GREATLY APPRECIATED AS THESE ISSUES HAVE DELAYED A BIG PROJECT. THANK YOU IN ADVANCE.
