portmap translation creation failed for tcp src inside:10.x.x.x/<random port number> dst outside:<internet IP address/port number>

We're able to get to the internet, but everyone has noticed a lag in response times so I decided to check the firewall.  Not sure if this is a major issue, but it is an error that I had not seen before.  Any ideas of what I can check?

 

Thanks,

 

Andrew

this  under some circumstances can be bug. But they usually not interrupt traffic.

 

I would suggest looking for how many PAT is already existed with this IP address. You can check "show xlate | in <pat ip address>" and see if the PAT ports are already exhausted. This usually happens because all users are using on one IP for PAT and connection is so high that all the ports got exhausted.

 

there are some questions through

1) are you using ASA in cluster mode?

2) what is the software version?

3) attach your running-config

Hi,

Output of "show nat pool" output would also be helpful in addition to your relevant NAT and ACL configuration.

Thanks and Regards,

Looking at PAT pool stats, this doesn't seem to be exhausted at any point. Opening a TAC case will be better option to dig deeper.

I ended up being more specific with the NAT statements.  Instead of having any - outside I changed many statements to <interface> - outside.  That seemed to clear it up.

1) Not in cluster mode

2) Cisco Adaptive Security Appliance Software Version 9.0(4)
Device Manager Version 7.1(6)

3) I'm not comfortable posting my running configuration.  I can just open a case if this is not enough information to go on.

Thanks,

Andrew
