        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 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 { 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.
