unable to reach public ip's.

ReinoutNL

Hi,

 

for a couple of month's now i've been having intermittenly problems with traffic thats going to public (IP) destinations. for instance everything is running smooth and all of sudden you can't resolve a page any more if you try to do a ping  to the DNS FQDN it won't work.

 

First i thought it was a DNS issue, but it wasn't. )The DNS servers are internal and are reachable and they forward the traffic to public DNS servers and thats where i noticed it when't wrong.  The firewall itself is reachable internaly but everything connected on the WAN port isn't from the LAN ip space.

 

I've switched the profiles of the IPS, I've double checked the firewall rules, i've scoured the logs (Thank god you guys are going to fix this in the 17 patch, right?) but to no avail. Is there anybody who knows why this is happening?

I've had this with versions running from 15.x.x to current latest firmware version. (home license)

Regards,

 

Reinout

    Hi,

     

    ping returns "No reply", no traffic to public ip's is at that point possible. The log's don't show anything specific. (or where would you look?, i checked the "firewall" and IPS logs) I see some activity based on DNS but that should block specific traffic not all traffic. for instance if i ping the ip 8.8.8.8 that doesn't respond.

    The whole firewall is up to date. nothing is lagging.

     

    Regards,
