ASA5505 Looses next hop and Internet drops.

ASA5505 drops Internet randomly. It lost it again yesterday and I was able to look at the logs and got this:

Dec 02 2007|15:15:16|110002|||Failed to locate egress interface for UDP from inside:192.168.x.x/1028 to 167.x.x.x/53

Dec 02 2007|15:15:06|110003|||Routing failed to locate next hop for UDP from inside:68.x.x.45/1 to outside:192.43.x.x/123 (68.x.x.45 is my external IP)

It looks like for some reason the ASA looses the dynamic route to the Internet. My IP is assigned dynamically by the ISP so what I decided to do is to statically put the IP route to the Internet as the gateway being the next hop. I used this: route outside 0.0.0.0 0.0.0.0 68.x.x.1 1. hopefully this fixes the problem with the ASA losing the Internet.

Has anyone seen this before? and if so will "route outside 0.0.0.0 0.0.0.0 68.x.x.1 1" fix the issue?

Any feedback would be great!

Thanks!

Have you tried using the statement 'ip address dhcp setroute' for the outside interface? This is required in order to obtain the default route using DHCP.

HTH,

I already have that set on the ASA. Could it be a hardware problem with the ASA?

That is certainly possible, but it's better to look at the software configuration first. If you can post a sanitized config of your device, we can help analyze it to look for issues.

Ok, here it is. Let me know if anyone sees anything wrong with the config. This is driving me crazy.

Thanks!

Everything looks correct to me, sorry that I can't help with this one!
