Forwarding rule misrouted at times
we have a Http-Paket filter rule forwarding traffic on one of our public IP addresses to an internal server on port 80 (static NAT).
For one customer it happens at times that the request is misrouted and leads to the Firebox SSLVPN Login website which causes an error. He says he always use the same URL http://xxx.yyy... The SSLVPN Login website is available on the same IP but only over https.
In the Dimenson Log Search there is traffic from that customer stopping exact at that time when he receives error. Traffic of other customers go on.
I can't see where the routing is that lead him to the SSLVPN Login site.
