Those options worked for me, too, except that dhcpd could not run on ppp interfaces (which did not necessarily even exist when dhcp3-server starts); I first had to add the “bcrelay eth0″ option to my pptpd.conf so dhcpd sees the DHCPInform messages.

There are dual-port PCI cards, I’ve recently looked at exactly IBM’s one. You should be able to find yours at ebay if doing a separate subnet is still a more desirable approach.

Here’s how I did it with dhcp-3:

# MS routes: adds extras to supplement routers option
option ms-classless-static-routes code 249 = array of integer 8;
# RFC3442 routes: overrides routers option
option rfc3442-classless-static-routes code 121 = array of integer 8;
option routers 172.22.0.1;
option ms-classless-static-routes 24, 172, 22, 99, 172, 22, 0, 1 ;
option rfc3442-classless-static-routes 24, 172, 22, 99, 172, 22, 0, 1,
0, 172, 22, 0, 1 ;

The ms- option has just one route, to 172.22.99.0/24 via 172.22.0.1 (yes, a portion of 172.22.0.0/16 is elsewhere; without the route the client would expect to find 172.22.99.0/24 on the LAN); RFC3442 says that if you use the option, you have to specify the default route too and that clients MUST ignore the routers option if present.
