Our server is co-located with an ISP who has provided small subnets for their clients to use. (ie 205.147.0.* for the ISP's machines, and 205.147.1-15.* for colocated machines and ISDN/T1 connections to customer's private office subnets) Our server is 205.147.5.82 and the netmask is 255.255.255.240. The router, which is on the same physical wire as the server, has the address 205.147.0.1. The problem is that when you specify the .0.1 address as the default gateway you get a "network unreachable" error. The usual solution, according to the ISP, is to manually add the default route _something_ like this... route add default 205.147.0.1 metric 0 Although this works fine on Solaris and Linux it fails on both BSDI and FreeBSD. A call to BSDI tech support was greeted with a real bad attitude "our system works the way it's supposed to! your ISP is a fool! WE CANT HELP YOU!" hrmph! so much for them :( Our temporary solution was to open up the netmask to encompass all subnets from .0 to .5, then manually add routes as necessary to the non-local subnets from .1 to .4 This will eventually lead to problems down the road if we get moved to a much higher subnet number, or if we open up multiple routes to the net... Has anyone got a better solution than opening up the subnet mask or switching OS's? Thanks in advance, Henry The ISP says the standard solution is to manually add a route _something_ like this route add default 205.147.0.1 metric 0
