Hello.
We use Sierra production in gas\oil automatization with thousands pcs.
Many time we used a bundle: Mikrtotik RB750UP + SIerra SL8082. All works fine. But recently we knows that SL8082, SL8083 production will stop. I try SL8082T as alternative, but now we fail to use RB750UP + SIerra SL8082T.
I contact with Mikrotik support, but they link to Sierra support.
Now i have next situation: Mikrotik successfull connect to network, get true ip address, dns servers, but any user data dropped. I see that data transfered to network, but no answer. On identical configuration with SL8082 all works good, so it’s not a Mikrotik firewall problem.
I can provide remote access (ssh) to Mikrotik device with SL8082T connected.
I think that reasonably engage Mikrotik tech support specialist into this thread.
Thanks.
Mikrotik connection log with SL8082T:
