Virtual Server to maintain the same destination port to the backend
I have a requirement where have 4 backend server listening or port range 1603-1699 i.e. a total of 96 ports. The requirement is that the Virtual server should listen on the same ports and when the VS receives a request on any port for example port 1610 the request to any of the four pool members should be forwarded on the same port no, which mean the destination port should be maintained end to end
My assumption is that if I disable the option "Translate Port" under the VS setting it can be done.
Can anyone help me affirm this or if not possible provide an alternate solution ?
- You can also keep port translation enabled if traffic destined on VIP port should be sent to same port on the pool member. This should work.
- You would need VIP defined on any port. Configure iRule to only allow specific range and discard traffic for other ports.
Please modify accordingly for start and end port range
when CLIENT_ACCEPTED { if {([TCP::local_port] >= <start port> && [TCP::local_port] <= <end port> ) } { return ) else reject }
- define pool with all 4 members and any port.
