Well here i am again.... I have a problem with IPs, see this: 

 --------- 
| Another | 
| Place   |-----R1-- (......) (a VPN Provider) --R2 -----  GW (Shorewall PC) 
------  My Net 
 ---------

Into the "Another Place" has 10.11.0.0/24 ips throw R1 connect to my R2 router 
(10.11.1.1), but my net has 10.11.0.0/24 address too, so when the GW PC get a 
packet from the "Another Place" has by example 10.11.0.2 ip, but in the dmesg 
command say as martian packet, i think that are because the R2 has 10.11.1.1 
address and not do NAT.

How i can configure shorewall that to respond to request from "Another Place" 
net that have the same address space that "My Net"??? note that i can change 
the address of "Another Place".

Now i have a rule that if connect to GW 10.11.1.2:3128 then do a DNAT to 
10.11.0.20:3128, but when a do a "tcpdump -i eth2" that is the interface with 
R2 i see the request from 10.11.0.2 to my 10.11.1.2:3128 well, but don't do the 
routing, i think that it is because the same address space in both place... 
thanks and rewards
