Unknown port blocking in SFOS 18.0.4 MR-4

s1s3at

Hi there,

I have updated from SFOS 18.0.3 MR-3 to SFOS 18.0.4 MR-4 last week. Im running the XG Home version on a zotax zbox ci327 nano.

Since updating I cannot access two specific destination ports: TCP 4443 and UDP 443, which are required. Browser, client and telnet/portqry (udp) - no response.

I have added additional FW rules but still no luck. Nothing in the logs, the connections are not even listed. I have checked all available log systems in the log viewer.

I have checked the policy tester, which provides positive results and mentions the specifically added fw rules. I have used telnet for the TCP Port via advanced shell: this works.

Now I have reverted to SFOS 18.0.3 MR-3 and right after booting and bringing up all services both connections work like a charm, without any change on my side. 

I could not find any associated topics in the release note of SFOS 18.0.4 MR-4. I have searched the web and this community, but could not find anything regarding this topic or similar to it either.

Any suggestions?

thx & br
