Problem in gif-tunnel creation

[regular]

Hallo all. I have to create vpn through 2 FreeBSD 10.0 gateways. With command line I do it successfully. But I cannot do it with rc.conf.

When I write in rc.conf

cloned_interfaces="gif0"
ifconfig_gif0="tunnel EXTIP1 EXTIP2"
ifconfig_gif0="inet 192.168.51.1 192.168.111.2 netmask 0xffffffff"

i receive

gif0: flags=8011<UP,POINTOPOINT,MULTICAST> metric 0 mtu 1280
	inet 192.168.51.1 --> 192.168.111.2 netmask 0xffffffff 
	inet6 fe80::76d4:35ff:fe13:3863%gif0 prefixlen 64 tentative scopeid 0x7 
	nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>

When I write in rc.conf (change line order)

cloned_interfaces="gif0"
ifconfig_gif0="inet 192.168.51.1 192.168.111.2 netmask 0xffffffff"
ifconfig_gif0="tunnel  EXTIP1 EXTIP2"

I receive

gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1280
	tunnel inet EXTIP1 --> EXTIP2
	nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>

What am I doing wrong?

The rc.conf file is a shell script and it uses the /bin/sh shell's variable assignment conventions. What you're now doing is first assigning one value to ifconfig_gif0 and immediately after it overriding the value with another one. Combine the two lines into one:

ifconfig_gif0="tunnel EXTIP1 EXTIP2 inet 192.168.51.1 192.168.111.2 netmask 0xffffffff"

In this case I receive

gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1280
   tunnel inet EXTIP1 --> EXTIP2
   nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>

but I change order parameters

ifconfig_gif0="inet 192.168.51.1 192.168.111.2 netmask 0xffffffff tunnel EXTIP1 EXTIP2"

and receive

 gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1280
	tunnel inetEXTIP1 --> EXTIP2
	inet 192.168.51.1 --> 192.168.111.2 netmask 0xffffffff

Thank you for your help!

Oh yea, the order seems to be important. What's in the variable is fed straight to ifconfig(8) that seems to be quite picky about the order.
