Guest ¡!Aidemin!¡ Posted October 8, 2007 Posted October 8, 2007 Hail! Is there any way to change the subnet mask configuration on a manually added static route on a DHCP server (Windows 2000 ou 2003) to one different than /32 (i.e. /16)? Thanks!!! -- ¡!Aidemin!¡ "MBA é o que dá o direito a uma abóbora de ser chamada de pumpkin"
Guest Ryan Hanisco Posted October 9, 2007 Posted October 9, 2007 RE: DHCP Static route Aidemin, I am a bit confused by your question as DHCP doesn't deal with routes. I will tell you that DHCP is not tied to any specific subnet mask and can use any valid one you give it. (/32 wouldn't work of course...) So, a change to any of the valid values that DHCP is pushing out would take effect the next time the workstations take a lease. If you have workstations that are statically set, the DHCP server will not be able to address them as it will only provide addresses and setting to machines configured to abide by the DHCP settings. I took as guess at what you're really asking, so please feel free to clarify. -- Ryan Hanisco MCSE, MCTS: SQL 2005, Project+ http://www.techsterity.com Chicago, IL Remember: Marking helpful answers helps everyone find the info they need quickly.

Guest ¡!Aidemin!¡ Posted October 9, 2007 Posted October 9, 2007 Re: DHCP Static route Ryan, Thanks for replying. If you go to DHCP Options or, on an address reservation on the same DHCP Options, tab General, you can go to the option number 033 (Static Route Option). On this option you can specify a destination address/router address( ie. 172.16.0.0/10.0.0.1). The problem is, even though the option is configured and implemented successfully, the route specified is auto-configured with a /32 subnet mask (255.255.255.255), thus, not reaching a /16 network as per specified in my example. My question is if there is any way to change this subnet mask to a more specific one through registry or any other tool. I have noticed that this "issue" occurs on either Windows 2000 Server or Server 2003 DHCP Servers (I could not yet perform the test on the Longhorn). Again, I thank you guys for the attention.

Guest Westmont Posted November 13, 2007 Posted November 13, 2007 Re: DHCP Static route Hi all, I had the same problem. I fixed it by using Option 249 (the last in the list) through which you can define a specific network mask. This option is called <Classless static routes> in the way you must determine the network mask. The option 033 corresponds to <Classfull static routes> for which the network mask is deducted according IETF RFQs. Working fine... Hope this will help.
