HI guys, I have a questions: I replaced a HP2626 Layer 3 switch with an SG 300-20 which is also configured to act as Layer3 Switch.
Now I have two Issues and maybe I'm just too blind to see the solution, but at the moment it's driving me nuts.
1. Behind the Switch are 2 Microsoft Forefornt Firewalls behing tagged Ports acting as a Loadbalancer/Failover. They have a common IP working over IGMP Multicase. Which is not reachable.
2. If I'm doing a traceroute for example to the Headquater the first Hop, the SG 300-20 is not shown.
1 * * * Zeitüberschreitung der Anforderung.
2 <1 ms <1 ms * 10.127.199.21
3 27 ms 26 ms 26 ms 10.127.198.3
4 27 ms 28 ms 27 ms 10.127.201.114
If I'm changing the Microsoft Forefont Firewall to work over Unicast the all problems nearly disappear. Traceroutes to the Company are working and the Loadbalanced IP is reachable, but the performance of the Forefronts is not usable, timeouts over and over again, thats why we where using IGMP Multicasts bevor.
Also over Unicasts the IP of the SG 300-20 is shown in the traceroute.
Thanks for your help.
