Σε Fritzbox 7360 (που βρήκα el cheapo στο ebay) προσπαθώ να σετάρω το VOIP.
O πάροχός μου (Vodafone) δίνει 2 vlan:
- 835 που υποστιρίζει ppp και είναι για internet
- 837 που είναι VOIP only.
Το σετάρισμα τoy δικτύου σε openwrt είναι:
config interface 'loopback'
option device 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'
config globals 'globals'
option ula_prefix 'fdd2:a40d:d919::/48'
config device 'wan_dsl0_dev'
option name 'dsl0'
option macaddr '00:20:da:86:23:75'
config atm-bridge 'atm'
option vpi '1'
option vci '32'
option encaps 'llc'
option payload 'bridged'
option nameprefix 'dsl'
config dsl 'dsl'
option annex 'b'
option ds_snr_offset '0'
option line_mode 'vdsl'
option tone 'auto'
# option firmware '/lib/firmware/vr9-B-dsl.bin'
config device
option name 'br-lan'
option type 'bridge'
list ports 'lan1'
list ports 'lan2'
list ports 'lan3'
list ports 'lan4'
config interface 'lan'
option device 'br-lan'
option proto 'static'
option ipaddr '192.168.1.1'
option netmask '255.255.255.0'
option ip6assign '60'
option ip4table '1'
config interface 'wan'
option device 'dsl0.835'
option proto 'pppoe'
option username 'guest@adsl.gr'
option password '******'
option ipv6 'none'
option keepalive '10'
option mtu '1492'
config interface 'voip'
option device 'dsl0.837'
option proto 'dhcp'
option defaultroute '0'
option ip4table '2'
config interface 'wan6'
option device '@wan'
option proto 'dhcpv6'
config rule 'lan_voip'
option in 'lan'
option src '192.168.1.0/24'
option lookup '2'
option priority '30000'
Και η διεπαφή VOIP έχει τα κάτωθι ifstat:

Όπου ΧΧ.ΧΧΧ.ΧΧ.ΧΧΧ είναι η IP για VOIP. Έτσι στα DNS του interface ορίζω τα εξής routes:
ip route add 62.38.86.50/32 via ΧΧ.ΧΧΧ.ΧΧ.ΧΧΧ
ip route add 62.38.86.40/32 via ΧΧ.ΧΧΧ.ΧΧ.ΧΧΧ
Και μετά βλέπω αν το ngn.hol.net (to domain του SIP server της Vodafone) γίνετε resolve:
nslookup ngn.hol.net 62.38.86.50
Server: 62.38.86.50
Address: 62.38.86.50:53
*** Can't find ngn.hol.net: No answer
*** Can't find ngn.hol.net: No answer
nslookup ngn.hol.net 62.38.86.50
Server: 62.38.86.50
Address: 62.38.86.50:53
*** Can't find ngn.hol.net: No answer
*** Can't find ngn.hol.net: No answer
Any ideas γιατί συμβαίνει αυτό;
Το ip rulew list μου βγάζει:
ip rule list
0: from all lookup local
10000: from 192.168.1.1 lookup 1
10000: from 10.222.62.225 lookup 2
20000: from all to 192.168.1.1/24 lookup 1
20000: from all to 10.222.62.225/19 lookup 2
32766: from all lookup main
32767: from all lookup default
90014: from all iif lo lookup 1
90015: from all iif lo lookup 2
Ακόμα το /etc/iproute2/rt_tables έχει:
cat /etc/iproute2/rt_tables
