Hello,
I have been using -current for a few weeks now after converting from
linux and then finding that a lot of things I wanted to do only work in
-current and not -stable. However the only thing which I can not get to
work exactly as it did in Linux on -current are my TCP/IP settings. I
have two ethernet cards, one which I use for outbound (default net)
traffic and its responses, and one card which I use for inbound port
forwards from my hardware router as well as inbound/outbound for my
192.168.1.0 net. I have been able to get this to work perfectly, but
only in 4.5-RELEASE (well actually in -stable, ie. 4.4-RELEASE,
4.5-RC{1,2,3}, and 4.5-RELEASE). Here is a small session which shows a
successful setup under -stable:

This shows no problems at all and works whether I use the routing daemon
or use static routes at boot up, however -current will not allow me to
do the same thing that I have done above, instead I get the following:
bash-2.05a# ifconfig -a
xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=3<rxcsum,txcsum>
inet 192.168.1.2 netmask 0xffffff00 broadcast 192.168.1.255

ppp0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
bash-2.05a# ifconfig xl1 192.168.1.3 netmask 255.255.255.0
ifconfig: ioctl (SIOCAIFADDR): File exists
The only thing which I can think of is that either a) it is a userland
change in -current, or b) I was only ever running the GENERIC kernel for
4.5-RELEASE and never recompiled my kernel until I was compiling with
-current source so maybe it is some option in the GENERIC config file
for the -current source. If it is b) could someone please tell me which
option is causing this so that I may turn it back off. I would really
like to try and get this working exactly as I have in Linux, Solaris,
FreeBSD 4.5-RELEASE. Thanks for any help.
