80 TopicsUse Specific Gateway Pool based on SNAT address
Hi All, Currently we have 3 ISP Links which I am trying to get routing correctly based on outbound SNAT. I have created SNAT Pools for the internal subnets that contain a IPs from each of the three ISPs. The F5 seems to be SNATing to one of the external IP's from the pool then using our Wildcard Server, Round Robin to send the traffic down any one of the three ISP links. This results in the traffic going down the right link only every other time. ISP A ISP B ISP C Internal 192.168.20.0/24 Current Issue F5 -> Snat addresses 192.168.20.0/24 to external IP from ISP A -> Round Robin and send down link ISP A, B or C I would like to configure it so the F5 uses the correct ISP link based on its SNAT address. Someone please tell me this is possible? Best Regards, Scott174Views1like0CommentsOutbound SNAT for servers: Destination Net Prohibited
Hi, Probably something simple ... I am trying to set up outbound connections for servers behind my F5 LTM. My assumption was that an outbound SNAT (using auto map)as per the configuration guides would accomplish this. Unfortunately not. When I do a test ping I get the message back from the Big IP: Destiantion Net Prohibited: When I configure a static NAT for a particular server everything is fine. The configuration guide does not mention any additional configuration required for this outbound snat scenario. I believe that NAT or SNAT should be sufficient to allow traffic through the LTM. For NAT this is the case. In the end I have created a "Forwarding IP" Virtual server for all source IPs and I have bound that to my internal interface. The Virtual server is suing "auto map" as well for source IP address translation. I would prefer to use the outbound SNAT and not the Virtual server. If someone could help identify the issue, I would appreciate it. Many thanks,1.7KViews1like4Comments
