Hi I've got two FreeBSD routers that act as redundant backups of each other using VRRP. Both these machines bind their own interfaces for administration purposes and the VRRP handles which one binds the gateway address. My problem is that, because the admin interface is bound before the gateway one, when I traceroute through the router I see the address of the admin interface rather than the gateway. So what I need to do is change the source address in the ICMP TTL exceeded messages that get sent out from the router to the gateway address. vrrpd lets me execute arbitary scripts when it becomes master/slave, so this shouldn't be a problem. The question is how do I actually change the source address?
