Thanks Ryan for replying,<br><br>I seriously need your help here,<br><br>We have dhcp ranges:-<br><br>dhcp-range=eth1,172.16.49.101,172.16.49.254,14400<br><div>dhcp-range=eth1,172.16.50.1,172.16.50.254,14400<br>dhcp-range=eth1,172.16.51.101,172.16.51.254,14400<br>
dhcp-range=eth4,172.16.56.20,172.16.56.254,14400<br>dhcp-range=eth3,172.16.52.21,172.16.53.254,14400</div><br>So none of the machines pull the 172.16.48.x ip addresses, however they do pull other ones like 49/50/51/52/56,apart from 49 series pulled from dhcp and 48 series if forced manualy, all other can ping 172.16.48.4.<br>
<br>For all the series which we have setup on eth1, i.e <br><div><br>dhcp-range=eth1,172.16.49.101,172.16.49.254,14400<br>dhcp-range=eth1,172.16.50.1,172.16.50.254,14400<br><div>dhcp-range=eth1,172.16.51.101,172.16.51.254,14400<br>
<br>We are trying to setup <b>172.16.48.4</b> as gateway, it works fine for 50/51 ips pulled by hosts but, dont work for 49 series,<br>and subnet which its lying under in vlan is 255.255.252.0<br><br>on Untangle<br> </div>

<br>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:<br>dhcp-range=eth1,172.16.49.101,172.16.49.254,14400<br>dhcp-range=eth1,172.16.50.1,172.16.50.254,14400<br>
dhcp-range=eth1,172.16.51.101,172.16.51.254,14400<br><br>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<br>and hence no internet for 49 series <br>
<br>Please suggest what can we do to resolve this.<br><br>-- <br><span style="color:rgb(31,73,125);font-size:9pt;font-family:arial,helvetica,sans-serif">Best Regards,</span><br style="color:rgb(34,34,34);font-size:13px;font-family:arial,helvetica,sans-serif">
