Traffic between different Vlans


Hi Team,


i just started with the F5 Big-IP as a firewall on my aws environment and i have two different Vlans

one is (the servers)

and the second is (DB subnet) and i try to make the two communicate with each other i did create a Virtual servers with Forwarding IP type but the tow Vlans still can not communicate with each other not even pinging, any help will be appreciated


Best Regards,

Forwarding virtual servers do not automatically pass ICMP :

K7366: Configuring BIG-IP LTM to pass ICMP traffic


You will also need to correctly specify the floating self IP as the gateway for the hosts.

hi the i already configured all the relevat traffic to go thru the Self iP each VLAN but also i think i might have configured something in a wrong way because ssh connections between the two vlans are not possible as well.


i did add the SNat thing but still no traffic being passed thrue
