Firewall blocking TCP:R packets
ok.. so here is my crazy issue that I can not seem to get worked out.
Firewall: NAT: Port Forward rule for port 25 SMTP from WAN interface –> Internernal IP of mail server port 25
Firewall: Rule setup to
Proto Source Port Destination Port Gateway
TCP/UDP * * 10.0.0.10 25 (SMTP) *
Now all INBOUND mail is working just fine. It is when I try to send an email that things stop working.
I see this in the firewall logs as being blocked by "Default deny rule" ..
Time If Source Destination Proto
Jun 15 18:03:32 WAN xx.xx.xx.xx:25 xx.xx.xx.xx:43402 TCP:R
What could I be missing...
bump…. If I can not find out why this is going on soon I will have to move to something else rather than pfSense..
someone has to have seen this before...
Mine is blocking TCP:R and TCP:F. ???
Blocking TCP:R (Resets) and TCP:F (Fin) can be normal, and not indicative of the actual problem.
