BT blocks block of static IPs

itmika — Thu, 22 Dec 2022 19:29:48 GMT

Hi,

I cannot ping another BT business static IP and whole block of IPs.

Pinging 81.150.33.x (BT static IP for email server) with 32 bytes of data: Request timed out.

It works fine from a BT 4G Assure stick and it works from other networks.

How to get BT to fix this?

I tried to call BT several times "static IP access is not BT responsibility"

Thank you,

Jac

Hi,

I switch the connection to 4G Assure backup internet and another peculiar problem shows when connecting to the same router dynamic IP or static IP (both on the same router).

Dynamic IP -> 81.139.113.x

Seems the problem lies inside BT, isn't it?

Any suggestions?

What else do you think I can check?

Thank you BT, for sorting this problem out.

All IPs are accessible now.
