I have been getting error MUDEC_00049: No entry for SID 318 as of today. I have tried fixes on this page http://mudfish.net/docs/en/support/firewall.html#firewall-issues, but to no avail,
It seems your issue is related with recent service outage of Mudfish (for details please check Service Outage Report - 20170217 link). Please let me know if your issue isn’t fixed yet.
