Re: RS also a client

[rkhamilton <rkhamilton@xxxxxxxxxxxx>]

Hey,

I was actually able to solve my customers problem by using simple 
outbound iptables masquerading.
Adding rules like:

iptables -t nat -A POSTROUTING -p tcp -s 172.16.10.0/24 --dport 80 -j 
MASQUERADE
alllowed for outbound natted connections from the web servers, as 
clients, to other web servers.
no iproute2 stuff required. I suspect that my configuration is not the 
same as you might have expected. The only path to the Internet is 
through the director.
Does this make sense?
