[NTLUG:Discuss] Linux - wet11 bridge

I've just set up an ethernet - wireless bridge, Linksys's wet11, and all 
is well with the connection to the access point, (which is now providing 
my link to outside).  I also set up NAT / ipmasquerading so that I can 
share the connection [as I'm only using one IP], and that sees to be 
working okay.  However, now that I've configured NAT, I find that I'm no 
longer able to connect to wet11's configuration pages [via the browser]. 
 I can connect the cable another computer's nic and connect to it just fine.

The way I configured it:  I installed a second nic in one of my 
computers and connected it to wet11, while leaving it's original nic 
connected to my hub.  On this computer I set up IP masquerading by 
adding following lines to /etc/rc.d/rc.local
====================
/sbin/ipchains -P forward DENY
echo 1 > /proc/sys/net/ipv4/ip_forward
/sbin/ipchains -A forward -i eth0 -j MASQ

iptables -t nat -A POSTROUTING -j MASQUERADE -o eth1 -s 192.###.#.0/24
====================
I'm also  using /etc/rc.d/rc.local to configure eth1  -  so above these 
previous commands, you'll see:
===================
ifconfig eth1 up
ifconfig eth1 ###.##.#.###

route add default gw ###.##.#.# eth1
==================

Anyone see any obvious, [or not so obvious], errors in the way I've done 
this?
