I'm getting a serious problem on my ASA 5540.
I've configure a NAT pool range (10.10.10.2-10.10.10.4) to acess a remote network.
This pool conteins 3 ip address, and only 3 hosts on my internal network can acess the remote network.
When a 4th host try to access the remote network, the ASA shows me the following error: "Err 3 - port map translation creation failed for....src LAN:x.x.x.x dst WAN:x.x.x.x (type 8, code 0)"
What should I do to solve the problem?
I got to use this range this way.
When using a pool of addresses, it is first come first serve.
global (WAN) 8 10.10.10.2-10.10.10.4 netmask 255.255.255.0
So the first host inside will be assigned 10.10.10.2, the 2nd will be assigned 10.10.10.3, the 3rd will be assigned 10.10.10.4. When the 4th host attempts to go out there are no addresses left in the pool for them. This is your issue. So you must add addresses to the pool if you have them or you must PAT (not NAT) the other connections to another address. Or take an address from the pool and use that for PAT. Does that make sense?
