Hello, Here's a patch for a first attempt at static leases for udhcpd. Included in the tarball are 2 files (static_leases.c, static_leases.h) and a patch against the latest cvs. In the config file you can configure static leases with the following format: static_lease 00:60:08:11:CE:4E 192.168.0.54 static_lease 00:60:08:11:CE:3E 192.168.0.44 Comments/suggestions/improvements are welcome. Wade
