15.7 Legacy Series / Manual WIFI adapter setup (WPA) WAN failover. It's safe to editing /etc/rc.conf?

« on: November 10, 2015, 11:13:31 pm »

Hi  I'm not pro or coder, simply an IT admin from Dolomiti, so in these days I try to  test OPNsense (running on eeepc) with simple wan failover feaures,  for my public network installation , for increase security level and monitoring stuffs plus (ifwork as expected) I will use dns resolver and squid for optimizing outbond traffic generated by road warrior on free hotspot and some of my server (smtp, imap and some else under synology box)

Well I look for wifi configuration compared like pfsense is missing, so i read and follow the basic guideline at https://www.freebsd.org/doc/handbook/network-wireless.html

for setup wifi interface, next my rc.conf:

Code: [Select]

# -- BEGIN BSD Installer automatically generated configuration  -- #
# -- Written on Mon Nov 9 12:44:35 UTC 2015-- #
keymap='it.iso'
# -- END of BSD Installer automatically generated configuration -- #
# Next do manual override for WLAN networks adapters failover setup#
# --Here is first adapter connected to a default route trought Hyperlan provider#
wlans_ath0="ath0_wlan0" #internal adapter ath0#
ifconfig_ath0_wlan0="ssid Babiz channel 6 WPA inet 192.168.3.2 netmask 255.255.255.0"
#--Here is second adapter connected to a backup route trought common Android Wi-Fi router smartphone 3G/4G#
wlans_urtw0="urtw0_wlan0" #external usb adapter urtw0#
ifconfig_urtw0_wlan0="ssid AndroidAP WPA inet 192.168.43.2 netmask 255.255.255.0"
In according to this I put wpa_supplicant.conf file entry for every two WPA Wireless network of course.
My configuration of interfaces with webui is the same, TCPv4 STATIC and plus I add group for gateway in System: Gateway Groups section as well look like all working! 



I guess a configuration lol but some little problem , does not start at boot process! Ho no! 

(Ex, for next reboot,of eee pc box,  gw should be down)


Well for fix it,  when I again connect to a shell and I do service netif start command print this on console:

ifconfig: SIOCIFCREATE2: Input/output error

ifconfig: inet: bad value

And I go to check status of GW return working as well.



Next i made little dns resolving test over it and all looks great.



Yes, all is great (127.0.0.1 go in timeout by a first lookup of google.jp, it take more more time to complete lol, second try is immediatly, and dns resolver works great too)

Next the big question is :

I will to put service netif start in some kind of RC script to run (or maybe RE-run?) at end of boot process ?
Is not a problem for me find and tweak the right rc script , but I don't really know if this stuff may be to compromise stability of OPNsense scripting/php/webui interaction.
Maybe Is possible to setup wifi wpa connections by other hands? (I don't see anithing on webui or wiki)

Well big thanks for any reply in advance and take a great congratulations to all dev,team for yours hard work on this project!
Bye!
