Awesome! Thanks so much for the information! That looks like it will
be a perfect work-around. I didn't know that you couldn't use multiple
IP's on an interface. I only have one IP on the internal card but I
have multiple on the external one. I'll have to do some research and
see if I should change that. Thanks again!
