All, I sure hope someone can enlighten me. I am having a weird routing issue. Everything works OK, except I can't access the the external interface from a machine on my internal network. See network map pdf at http://www.marktaff.com/network.map.pdf See output of `ifconfig` and `route` below. From any internal (192.168...) machine, I can't ping/ssh liberty1-ext, but I can ping/ssh to liberty1-int. From each internal machine, I can reach all the other internal machines, and the router's external ip, but not liberty1's external ip. From outside my private network, I can ping/ssh liberty1-ext just fine. I want to be able to access the machine via liberty1-ext both at home and while traveling, yet still be able to access the private network from liberty1 via liberty1-int interface. Could the problem be my hub? Do I need to replace it with a switch, or perhaps a separate router? Seems like the hub should work? Thanks for all your help. -- Mark A.
