TOPIC: ASA 5505 Outside interface crashing

ASA 5505 Outside interface crashing 8 years 4 weeks ago #27230

Hello,

I have a ASA 5505, seems to run pretty smooth but almost 4 or 5 times a week, the outside interface goes out. Internet, Email, everything. Could a misconfiguration cause this problem? To fix it and get the outside interface backup again I just do a system reload and that fixes it, for a few hours at least....

Here is my show run.

Thanks a lot!

What's the outside connected to? if your outside is connected to an "always on" link, you shouldn't have problems.

Hello,

I have a ASA 5505, seems to run pretty smooth but almost 4 or 5 times a week, the outside interface goes out. Internet, Email, everything. Could a misconfiguration cause this problem? To fix it and get the outside interface backup again I just do a system reload and that fixes it, for a few hours at least....

Thanks for the reply.

The outside interface is connected to our ISP...

I would assume its a always on link.

You can try to send keepalives to the outside and see if your ocnnection stays up.
