i don't know if you'll get the assistance you seek on the list... if you
like, email me your ipchains congif file and i'll take a look and see if
i can figure out what it is that is happening... it may be all tied up
in the forward chain if it is as i imagine it may be currently
configured... also note that a lot also has to do with the addresses
that are being used to try to access the perproxy... it seems that you
are telling us (tinu) that "ipchains -L" is returning with the
following...

Chain input (policy ACCEPT):
target     prot opt     source                destination          ports
ACCEPT     udp  ------  hoshi.msi.net.ph     anywhere             
domain ->   1025:65535
ACCEPT     tcp  -y----  anywhere             anywhere             
any    ->   ftp
ACCEPT     tcp  -y----  anywhere             anywhere             
any    ->   telnet
ACCEPT     udp  ------  anywhere             anywhere             
bootps:bootpc ->   bootps:bootpc
ACCEPT     udp  ------  anywhere             anywhere             
bootps:bootpc ->   bootps:bootpc
ACCEPT     all  ------  anywhere             anywhere              n/a
ACCEPT     all  ------  anywhere             anywhere              n/a
REJECT     tcp  -y----  anywhere             anywhere             
any    ->   0:1023
REJECT     tcp  -y----  anywhere             anywhere             
any    ->   nfs
REJECT     udp  ------  anywhere             anywhere             
any    ->   0:1023
REJECT     udp  ------  anywhere             anywhere             
any    ->   nfs
REJECT     tcp  -y----  anywhere             anywhere             
any    ->   x11:6009
REJECT     tcp  -y----  anywhere             anywhere             
any    ->   xfs
Chain forward (policy ACCEPT):
Chain output (policy ACCEPT):

i see at least one rule that appears to be duplicated (the bootps:bootpc
one)... however, with a default rule of ACCEPT, the input chain would
appear to not need any rules other than your explicit REJECT rules... my
understanding and implementations have all started with a default rule
of DENY and then i add in any necessary ACCEPT and such rules...

another piece of info that is needed is the IP addresses of the systems
involved... this is one very important piece of info but i can
understand if security concerns caution you to not post them...
