ISP's who assign unrouteable addresses
My company has encountered two ISP's, US West and MediaOne, who assign
unrouteable addresses (10.x.x.x) to some of their customers. The ISP's
run NAT in the head-end of their cable network or ADSL network to translate
those addresses before they hit the Internet.
Obviously, an end-user wanting IPSEC is in trouble.
Any thoughts about how to deal with this problem? I personally don't
mind NAT if it is performed at the boundary between a stub network
and the Internet. The owner of that network can NAT and employ a
security gateway if he needs IPSEC.
On the other hand, I think ISP's that use NAT are short-changing their
customers. Is there anything we can offer a customer who is stuck
with one of the unrouteable addresses?
