I have a FreeBSD transparent proxy working on local lan. Where the
has its gateway set to the proxy server's internal ip address. Everything
Problem is when I move my workstation from the local lan where the proxy
server resides, on to the 10.4.0.0 network, this is across a WAN link,
Transparent proxy stops working it appears no web traffic is getting to the
proxy, and I'm not able to get to ant web site. I am able to ping the proxy
server, and use the proxy if I utilize a pac file, and drop the IPFW rules.
I should also note that I have transparent proxy running under Debian using
iptables, across the WAN link, but want to move to FreeBSD. So I feel my
routers are setup correctly.
I suspect the problem is with my IPFW rules or NAT configuration but I'm not
Kernel was recompiled with:
ifconfig_xl0="inet x.x.x.x. netmask 255.255.255.0"
ifconfig_xl1="inet x.x.x.x netmask 255.255.255.0"
CISCO router has the following configured
access-list 199 permit tcp 10.4.0.0 0.0.255.255 any eq www
access-list 199 deny ip any any
route-map redirect-proxy permit 10
match ip address 199
set ip next-hop <proxy server internal ip>
My IPFW rules:
ipfw -q flush
ipfw add divert natd all from not me to any via <outside interface>
ipfw add fwd 127.0.0.1:8000 tcp from any to any 80
squid complied with
header_access Via deny all
header_access X-Forwarded-For deny all
