For inbound connections from a client, a SNAT translates the source IP address within packets to a BIG-IP system IP address that you or the BIG-IP system defines. The destination node then uses that new source address as its destination address when responding to the request.

Like a standard SNAT, an intelligent SNAT is the mapping of one or more original IP addresses to a translation address. However, you implement this type of SNAT mapping within an iRule instead of by creating a SNAT object.

2015年9月22日 · A SNAT can be used by itself to pass traffic that is not destined for a virtual server. For example, you can use a SNAT object to pass certain traffic (such as DNS requests) from an internal network to an external network where your DNS server resides.

2020年10月23日 · You want to create a SNAT, automap SNAT, or SNAT pool using the TMOS shell (tmsh) or the Configuration utility. You want to create a data group SNAT mapping using iRules. For more information about SNAT and SNAT …

2018年11月30日 · F5 recommends that you ensure that you have configured floating self IP addresses on all VLANs from which you expect SNAT traffic to egress. Alternatively, you can mitigate the issue by using a SNAT pool with an IP address on the egress subnet VLAN as a member for the SNAT pool.

2012年9月7日 · Whether you’re just getting your start in Application Delivery and SNAT, or you’re a veteran who never took the time to understand what automap is and how address translation works with the F5 ® BIG-IP ®, I’m confident you will find this information indispensable.

2023年6月7日 · snat automap uses the egress vlan interface ip. by establishing a snat pool, and attaching, you can control what IP this translates to. Routed, client source address goes to the server. Routes necessary back through BIG-IP on servers or servers gw.

If you want to load balance requests to server nodes that are on the same network as the client nodes, you can create a SNAT so that server responses are sent back through the virtual server, rather than directly from the server node to the client node.
