I get error: NAT unable to reserve ports with this configuration

Hi,

I can only assume that this is related to using the "interface" IP address of the ASA and perhaps using VPN on that interface.

Then again a quick test on my own ASA after removing all VPN related configurations the ASA still wont accept the configuration. Though I wouldnt be surprised if a reload/reboot helped in my case.

Re: I get error: NAT unable to reserve ports with this configura

I do have site to site VPN tunnels configured. Is there any way to resolve this? I can't bring up the tunnel on the netgate and I have rebooted.

Patrick,

If you have a site-to-site then these ports are already being used for the interface IP.

Do you have another IP? you cannot use the same addres with same ports.

Regards,

Felipe.
