The NAT of the Cisco IOS Software can distribute subsequent TCP connections and UDP sessions over multiple network connections, if equal-cost routes to a given destination are available.This document does not describe a mechanism to differentiate between the routes; thus, there is no way to prefer a more-desirable connection over a less-desirable connection.
Cisco Nat Failover Dual Isp Software Version IsIf a different software version is used, some features are possibly not available, or the configuration commands cab differ from those shown in this document. Similar configuration should be available on all Cisco IOS router platforms, although the interface configuration likely varies between different platforms. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command. Examples of traffic that require this behavior include IPsec VPN clients, VoIP telephony traffic, and any other traffic that should always use only one of the ISP connection options to prefer the same IP address, higher speed, or lower latency on the connection. In cases where static IP addressing is applied, as opposed to DHCP-assigned addresses or PPPoE, and a WAN failure occurs such that the Ethernet port still maintains the Ethernet link to the WAN connectivity device, the router continues to attempt to load-balance connectivity across both the good and bad WAN connections. ![]() Cisco Nat Failover Dual Isp Verification That InsideThis command provides verification that inside hosts are being translated to both NAT outside addresses. Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP.
