As I understood it, that is exactly what OP has.  I was interested
because his problem is similar to mine where I have

 ISP -->GPRSmodem--> usb -- Eth1 --> router --> home lan
                   '---computer---'

(In that setup, I can only activate external or internal networking, but
not both at once.  The issue is I think my imperfect understanding of
routing, particularly how to achieve a different default route for
inward and outward traffic.  It is compounded by the fact that DHCP
rewrites resolv.conf, and pppd rewrites the routing table. Any
corrections I make are immediately overwritten.)
