Extrange behavior using ppp, pf and altq on FreeBSD 5.3

Please help!
I am new to FreeBSD, and UNIX in general but form the beginning I'm
fascinated. I had configured a FreeBSD 5.3 machine to be the
Firewall/gateway of 8 windows PC's. The machine has 2 interfaces one
(fxp0) is connected to the ADSL modem and the another (rl0) is
connected to a switch where the windows boxes are connected too. The
first problem is that sometimes, when ppp redial to the pppoe Internet
provider, I can use Internet from the FreeBSD machine, but not from
the internal network. I had found a workaround to this problem:
--------------------------------
server:~ $ cat /etc/ppp/ppp.linkup
default:
! pfctl -F all -f /etc/pf.conf && /usr/local/etc/ez-ipupdate.conf
---------------------------------
Refreshing the pf rules, the nat appears to work again, after a connection drop.
The problem that I can't solve is the following:
In the FreeBSD manual states that one must use router_enable="NO" in
rc.conf, to avoid routed to delete the routes added by ppp. If I do
this, I can't have access to the box from outside using ssh.
For reference I added the content of the floowing files:
/etc/rc.conf
/etc/start_if.tun0
/etc/ppp/ppp.conf
/etc/pf.conf
/root/kernels/GENERICconALTQ # the kernel config file
demesg
Thank you very much!!!
