Hi All,
I have Untangle with DNS masq setup at my end,
With interface:
External
eth0 Link encap:Ethernet HWaddr 00:04:23:c7:52:63
inet addr:172.16.57.10 Bcast:172.16.57.255 Mask:255.255.255.0
INTERNAL
eth1 Link encap:Ethernet HWaddr 00:04:23:c7:52:62
inet addr:172.16.48.4 Bcast:172.16.51.255 Mask:255.255.252.0
DMZ
eth2 Link encap:Ethernet HWaddr 00:1b:21:0e:1f:46
inet addr:172.16.48.110 Bcast:172.16.49.255 Mask:255.255.254.0
Extra ones:
eth3 Link encap:Ethernet HWaddr fc:75:16:8e:57:2b
inet addr:172.16.52.20 Bcast:172.16.53.255 Mask:255.255.254.0
eth4 Link encap:Ethernet HWaddr fc:75:16:8e:57:42
inet addr:172.16.56.2 Bcast:172.16.56.255 Mask:255.255.255.0
Now my dnsmasq.conf,
localise-queries
server=202.56.224.135 # uplink.1
server=59.144.127.16 # uplink.1
expand-hosts
addn-hosts=/etc/untangle-net-alpaca/dnsmasq-hosts
no-hosts
domain=bpl.netlink.com
interface=eth1
interface=eth3
interface=eth4
dhcp-range=eth1,172.16.49.101,172.16.49.254,14400
dhcp-range=eth1,172.16.50.1,172.16.50.254,14400
dhcp-range=eth1,172.16.51.101,172.16.51.254,14400
dhcp-range=eth4,172.16.56.20,172.16.56.254,14400
dhcp-range=eth3,172.16.52.21,172.16.53.254,14400
dhcp-option=eth1,3,172.16.48.1
dhcp-option=eth4,3,172.16.56.1
dhcp-option=eth3,3,172.16.52.1
dhcp-option=eth1,1,255.255.252.0
dhcp-option=eth4,1,255.255.255.0
dhcp-option=eth3,1,255.255.254.0
dhcp-option=eth1,6,172.16.48.146,172.16.48.147
dhcp-option=eth4,6,172.16.48.146,172.16.48.147
dhcp-option=eth3,6,172.16.52.3,172.16.48.146
dhcp-lease-max=500
dhcp-host=00:13:02:a9:8b:57,172.16.48.106,24h
dhcp-host=94:39:e5:e6:a7:cf,172.16.48.208,24h
Now the issue is that i when we assign the ips with dnsmasq running with
multiple subnets as mentioned we face issues with range 49:
dhcp-range=eth1,172.16.49.101,172.16.49.254,14400
dhcp-range=eth1,172.16.50.1,172.16.50.254,14400
dhcp-range=eth1,172.16.51.101,172.16.51.254,14400
it assigns the 50 and 51 series fine with internet access but when assigns
49 series ip cant ping the untangles internal ip:172.16.48.4
and hence no internet for 49 series
Please suggest what can we do to resolve this.
