https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D269770 Bug ID: 269770 Summary: libalias udp redirect_port temporary translation failure Product: Base System Version: 13.1-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: pmc@citylink.dinoex.sub.org I occasionally observe temporary failures on my public UDP ports. The problem seems to be with libalias when used for UDP port_redirect: ipfw nat 3 config log same_ports unreg_only ip <public-ip> \ redirect_port udp 192.168.xx.xx:5007 5006 \ redirect_port tcp 192.168.xx.xx:5007 5006 02420 0 0 count log proto ip4 src-port 64000-64010 02425 0 0 nat 3 proto ip4 02430 0 0 count log proto ip4 src-port 64000-64010 Then randomly # nc -u4p 64000 <public-ip> 5006 # nc -u4p 64001 <public-ip> 5006 # nc -u4p 64002 <public-ip> 5006 Feb 23 03:51:45 <security.info> edge kernel: [75643] ipfw-oper: 2420 Count = UDP 91.12.117.156:64000 <public-ip>:5006 in via tun3 Feb 23 03:51:45 <security.info> edge kernel: [75643] ipfw-oper: 2430 Count = UDP 91.12.117.156:64000 192.168.xx.xx:5007 in via tun3 Feb 23 03:52:08 <security.info> edge kernel: [75666] ipfw-oper: 2420 Count = UDP 91.12.117.156:64001 <public-ip>:5006 in via tun3 Feb 23 03:52:08 <security.info> edge kernel: [75666] ipfw-oper: 2430 Count = UDP 91.12.117.156:64001 192.168.xx.xx:5007 in via tun3 Feb 23 03:52:29 <security.info> edge kernel: [75687] ipfw-oper: 2420 Count = UDP 91.12.117.156:64001 <public-ip>:5006 in via tun3 Feb 23 03:52:29 <security.info> edge kernel: [75687] ipfw-oper: 2430 Count = UDP 91.12.117.156:64001 192.168.xx.xx:5007 in via tun3 Feb 23 03:52:36 <security.info> edge kernel: [75694] ipfw-oper: 2420 Count = UDP 91.12.117.156:64001 51.158.21.23:5006 in via tun3 Feb 23 03:52:36 <security.info> edge kernel: [75694] ipfw-oper: 2430 Count = UDP 91.12.117.156:64001 192.168.98.18:5007 in via tun3 Feb 23 03:52:56 <security.info> edge kernel: [75714] ipfw-oper: 2420 Count = UDP 91.12.117.156:64002 <public-ip>:5006 in via tun3 Feb 23 03:52:56 <security.info> edge kernel: [75714] ipfw-oper: 2430 Count = UDP 91.12.117.156:64002 192.168.xx.xx:5007 in via tun3 Feb 23 03:53:06 <security.info> edge kernel: [75724] ipfw-oper: 2420 Count = UDP 91.12.117.156:64000 <public-ip>:5006 in via tun3 Feb 23 03:53:06 <security.info> edge kernel: [75724] ipfw-oper: 2430 Count = UDP 91.12.117.156:64000 <public-ip>:5006 in via tun3 Feb 23 03:53:06 <security.info> edge kernel: [75724] ipfw-oper: 2685 Unreac= h 13 UDP 91.12.117.156:64000 <public-ip>:5006 in via tun3 In the beginning 64000 and 64001 get through. Now only using 64001 for some time, and then starting to use 64002, suddenly 64000 is no longer translated. (Not always happens in that exact sequence.) # ipfw nat show log nat 2: icmp=3D32, udp=3D1, tcp=3D40, sctp=3D0, pptp=3D0, proto=3D0, frag_id= =3D0 frag_ptr=3D0 / tot=3D73 nat 3: icmp=3D0, udp=3D2, tcp=3D72, sctp=3D0, pptp=3D0, proto=3D0, frag_id= =3D0 frag_ptr=3D0 / tot=3D74 These udp=3D counters are changing meanwhile, but I don't get a clue from it, and didn't find a way to log details.
