changing destination IP in an iRule
I'd like to use BIG-IP to forward through a router normally, and if a particular pool is down, I'd like to change the destination IP of the packet to that of a distant (remote) proxy server before for...
Well, you could use the LINK::nexthop command to return the MAC address of the next logical hop in the transmission, which should get you the MAC info you're looking for.
The problem then is, there's no real way to specify this along with the IP address of the pool member. I can't think of any commands in iRules that would help you set that arp entry or use the MAC information to forward the request there.
