Hi, I have a two-interface shorewall setup with one side on a 192.168.0.0 network while the other is connected to the Internet via a cable modem.
There's a Win10 machine on the internal network that appears to be sending out snmp requests to the network printer, and I can't understand why shorewall is rejecting them. Dec 20 19:50:43 orion kernel: Shorewall:FORWARD:REJECT:IN=eth1 OUT=eth1 MAC=0c:c4:7a:a9:18:df:52:54:00:52:6b:61:08:00 SRC=192.168.1.18 DST=192.168.1.104 LEN=106 TOS=0x00 PREC=0x00 TTL=127 ID=17640 PROTO=UDP SPT=50731 DPT=161 LEN=86 In my policy file I have allowed internal to internal communications: int int ACCEPT I've also checked to make sure there aren't any explicit rules to block port 161 or snmp. Does anyone have any idea what could be causing this, or how I can troubleshoot it further? How do I identify which rule is causing this to be rejected? ------------------------------------------------------------------------------ Developer Access Program for Intel Xeon Phi Processors Access to Intel Xeon Phi processor-based developer platforms.
