I took over the administration of two cisco asa 5510 and one 5505 which are connected together over a L2L VPN and a RA VPN to access the main site.
The diagram of the network is some like this:
Default ISP GW 1.1.0.255
Outside IP 1.1.2.1 1.1.0.1 1.1.3.1
Name Site A ----------- HQ --------------- Site B
Inside IP 192.168.2.0/24 192.168.0.0/24 192.168.3.0/24
|
RA VPN
192.168.4.0/24
Everybody can access all resources on HQ but only HQ can access all resources on site A. Site B and RA VPN users can't access resources on Site A.
So when I login to the office(HQ) via RA VPN and try to access a server on site A, say 192.168.2.5, cisco routes the traffic out to the internet...
I have the following configuration, not the hole very long one....
access-list Inside_nat0_outbound extended permit ip 192.168.0.0 255.255.255.0 192.168.2.0 255.255.255.0

Apreciate any help. Ahh, and I am a cisco noob :-)

access-liststatements have the source and destination the wrong way round. For instance, youroutsideaccess-list allows all traffic from192.168.0.0/24to192.168.2.0/24, whereas from your diagram it looks like192.168.0.0/24is on the inside, not the outside. – Andy Smith Dec 19 '10 at 12:31
