Network firewall rule ignored. Packets drop by default rule (6002)

Antonio Bover

We are getting Default Drop for some traffic that should be allowed in Sophos UTM

Firmware version: 9.605-1

These rules are configured with the same public IP. 

Only traffic for rules 177 and 178 is being blocked

Firewall log shows this message:

2023:08:03-09:44:50 utm ulogd[4916]: id="2001" severity="info" sys="SecureNet" sub="packetfilter" name="Packet dropped" action="drop" fwrule="60002" initf="eth0" outitf="eth0" srcmac="02:8d:f2:17:73:d0" dstmac="02:50:85:4f:07:5c" srcip="10.27.34.109" dstip="163.166.x.x" proto="6" length="52" tos="0x00" prec="0x00" ttl="116" srcport="53855" dstport="8446" tcpflags="SYN" 

Does anyone know what could be happening for this dropped packets?

Thanks

    Hello  , 

    Thank you for reaching out to the community, yes indeed this is a default drop for the dstport 8446, SYN packet. Can you please create a new firewall rule on the top and then check ?

    Rule 60002 generally means the traffic was not destined for Sophos UTM, no firewall rule matched that packet, and no transparent interception was applied. This is known as a "Default drop" because, by default, packets without matching firewall rules are dropped.

    To fix this issue, create a firewall rule matching the traffic's source, service, and destination. If transparent interception should apply, check that the source or destination host/network is not included on a transparent interception skip list.

    Thanks & Regards,

    Hi Vivek,

    Thanks for your reply. I created a new firewall rule on the top. It's a "user created rule" but there are many automatic (from server load balancing) rules that have a higher priority. My rule on the top gets the number 186 so it didn´t change anything. 

    Another question, how could I edit my first post? I forgot to remove the public IP Slight smile

    Thanks,

    Regards
