I am writing a device driver for the Western Digital 8003e ethernet card on an IBM RT running AOS4.3 (the BSD4.3 port) and its coming along well but I have run into a problem. When the new interface (wd0) is ifconfiged and the existing interface (un0) is ifconfiged down all TCP traffic dies, and the only UDP traffic (NFS and NTP) is to/from machines listed in the "/etc/hosts" file. ICMP traffic is unaffected - in fact ping to/from this machine works great. I have traced this problem in the telnet code to the "connect" call - this guy fails with a timeout error. Any suggestions??? Thanks again. Mike
