after upgrade some masq rules not working

insti
Hi,

We have several public ip addresses defined as additional addresses on the public interface. These addresses have their own nat and masquerading rule.

After the last upgrade ( to version 9.102-8 ) some of these no allow any kind of traffic.

I have tried to disable/enable, deleting/adding interfaces and rules whitout positive result.

Could you help me?

Regards.

    Hi, insti, and welcome to the User BB!

    Please show a related line or two from the log files: firewall, intrusion prevention, etc.

    Cheers - Bob

    We have enabled ssh access on the firewall and analyzed the public interface with the help of tcpdump to verify the existence/non-existence of incoming packets on various IP.  The problem was in the ISP router that blocked itself  the connection table due to a DOS attack. Fixed it by rebooting the ISP router.

    Thanks you very much for your attention

    Regards.
