Until we know what the problem is, we can't guess at the solution. You didn't show the commands you used, for setting up the routes *or* for the diagnostic information you provided. > -Jin > > > Internet: > Destination Gateway Flags Refs Use Netif Expire > default 10.234.16.1 UGS 0 2841993 em0 > 10.227.148.52 10.234.37.80 UHS 0 26 ue0 There's no "G" in the flags there.
