      I just commited a change to install both tcp and udp entries for reflection.  I am guessing this was the only bug that you are experiencing but its rather hard to tell from re-reading your text.

          OK i made three rules 1 udp only 1 tcp only and one tcp/udp

          19000  stream  udp    nowait/0        nobody  /usr/bin/nc nc -u -w 20 10.250.100.129 161
          19002  stream  tcp    nowait/0        nobody  /usr/bin/nc nc -w 20 10.250.100.129 80
          19004  stream  tcp/udp nowait/0        nobody  /usr/bin/nc nc -u -w 20 10.250.100.129 123
          19005  stream  tcp/udp nowait/0        nobody  /usr/bin/nc nc -w 20 10.250.100.129 123

          NAT Inbound Redirects

          rdr on vlan1 proto udp from any to 192.168.50.254 port { 161 } -> 10.250.100.129

          Reflection redirects

          rdr on $lan proto udp from any to 192.168.50.254 port { 161 } -> 127.0.0.1 port 19000

          rdr on vlan1 proto tcp from any to 192.168.50.254 port { 80 } -> 10.250.100.129

          Reflection redirects

          rdr on $lan proto tcp from any to 192.168.50.254 port { 80 } -> 127.0.0.1 port 19002

          rdr on vlan1 proto { tcp udp } from any to 192.168.50.254 port { 123 } -> 10.250.100.129

          Reflection redirects

          rdr on $lan proto tcp from any to 192.168.50.254 port { 123 } -> 127.0.0.1 port 19004
          rdr on $lan proto udp from any to 192.168.50.254 port { 123 } -> 127.0.0.1 port 19005

          the rdr rules and the streams reconcile fine. but the localhost rules are messed up

          NAT Reflection rules

          pass in quick on $lan inet proto udp from any to $loopback port 19000 keep state label "NAT REFLECT: Allow traffic to localhost"
          pass in quick on $lan inet proto tcp from any to $loopback port 19001 keep state label "NAT REFLECT: Allow traffic to localhost"
          pass in quick on $lan inet proto tcp from any to $loopback port 19002 keep state label "NAT REFLECT: Allow traffic to localhost"
          pass in quick on $lan inet proto udp from any to $loopback port 19002 keep state label "NAT REFLECT: Allow traffic to localhost"

          as you can see there is nothing on 19001 and on 19002 there should only be tcp and there is nothing on 19003 or 4

                NAT Reflection rules

                pass in quick on $lan inet proto udp from any to $loopback port 19000 keep state label "NAT REFLECT: Allow traffic to localhost"
                pass in quick on $lan inet proto tcp from any to $loopback port 19001 keep state label "NAT REFLECT: Allow traffic to localhost"
                pass in quick on $lan inet proto tcp from any to $loopback port 19002 keep state label "NAT REFLECT: Allow traffic to localhost"
                pass in quick on $lan inet proto udp from any to $loopback port 19003 keep state label "NAT REFLECT: Allow traffic to localhost"

                the below is same for rdrs and inetd streams

                rdr on $lan proto udp from any to 192.168.50.254 port { 161 } -> 127.0.0.1 port 19000
                rdr on $lan proto tcp from any to 192.168.50.254 port { 80 } -> 127.0.0.1 port 19002
                rdr on $lan proto tcp from any to 192.168.50.254 port { 123 } -> 127.0.0.1 port 19004
                rdr on $lan proto udp from any to 192.168.50.254 port { 123 } -> 127.0.0.1 port 19005

                19000  stream  udp    nowait/0        nobody  /usr/bin/nc nc -u -w 20 10.250.100.129 161
                19002  stream  tcp    nowait/0        nobody  /usr/bin/nc nc -w 20 10.250.100.129 80
                19004  stream  tcp/udp nowait/0        nobody  /usr/bin/nc nc -u -w 20 10.250.100.129 123
                19005  stream  tcp/udp nowait/0        nobody  /usr/bin/nc nc -w 20 10.250.100.129 123

                    very close now

                      Commited.  Either search filter.inc for 18999 and change to 19000 or update to the latest RELENG_1 file.
