Have ISAPI on a front end that is multihomed on IIS 6. Has 3 IP's as the firewall won't multinat. Has IP's .19 .36 & .49, in that order bound to the NIC. The request is being proxied to a web server behind the front end.

Problem is that request is made to .49 but the request to the back end comes from the first IP address .19

Can it be overridden?

No, ISAPI_Rewrite's proxy can not specify which IP address will be used as a subrequest source.
But you could try to add explicit route to the backend server's IP through .19 address. It could be done with the command like (if both target and source are on the same network segment):

route add ddd.ddd.ddd.ddd mask 255.255.255.255 yyy.yyy.yyy.19 -p

Note that command should be run after each server reboot.
