I don't understand why 2 routers. Maybe I'm missing something. Unless you have 2 networks  that need to be separate only one is needed. If you have a wireless router, use it as a wireless access point and not a router. Which means turn off DHCP on the wireless router and don't configure or use the WAN connection. 
Depending on the capabilities of the router you can connect a LAN port on Router2 to your ADSL (Router1) router and assign an IP address that's in the same network as Router1.

Thanks, but I only have a very limited understanding of this matter.
Does this mean I had to add netfilter to the kernel and configure
iptables ?

Hey guys... it would help if you trim your posts so there isn't so
much in each message.

By correct gateway  I think in this case it would be the inward facing
address of pc1 (192.168.2.43) so on router2 you would set the gw to
that address. 
And on pc2 the gw would be  192.168.2.1.  That is unless router2 is
just a WAP (wireless access point). 
 
But I'm not sure I understand all of this.  It might be good to
include the make of the routers (even model number might matter).

Excuse me if this info is already in these monster size messages
somewhere but:
If you redo the diagram please include this information:
make and model of router2
What OS is running on pc1 and pc2

Annotate in one line what gateways are set at the various points.

The adsl router make and model may not matter too much.

I agree, but Richard, (and this is just a request from a confused
participant) please take a moment to pare down your reply and then
insert your message where it makes some sense, don't just blob it on
top and further confuse things.
