<p><b>New page</b></p><div>[[FAQs|All Untangle FAQs]]<br />
<br />
==How do I determine the devices that are attached to my network?==<br />
<br />
Assuming the Untangle Server is your router, you can locate the list of devices as shown in [[DHCP Server#Assigning Network Computers Static IP Addresses|Assigning Network Computers Static IP Addresses]].<br />
<br />
<br />
==If I am running NAT, how can I provide access to a web server connected to the internal network?== <br />
<br />
# If the web server is using DHCP, it should be assigned a static address. Go to [[DHCP Server#Assigning Network Computers Static IP Addresses|Assigning Network Computers Static IP Addresses]].<br />
# Map the web server to that IP address as discussed in [[DNS Server#Mapping Computer Hostnames To IP Addresses|Mapping Computer Hostnames To IP Addresses]].<br />
# Create a port forward rule for all incoming traffic on port 80 to your web server as discussed in [[Port Forward Rules]].<br />
<br />
<br />
==I have multiple subnets and after installing Untangle as a bridge only my main subnet can connect to the internet. Why?==<br />
<br />
Untangle needs to know about the other subnets in order to correctly route traffic to them.<br />
This can be done in several ways.<br />
# Give Untangle an alias on each subnet. This can be done in config->networking. This tells untangle that this subnet is local and should be routed accordingly.<br />
# Alternatively, If your subnets are all similar (ie 192.168.1.x vs 192.168.2.x) make sure Untangle has a netmask that includes them all (255.255.0.0 vs 255.255.255.0)<br />
# If your other subnets are behind another internal router also add routes to tell Untangle how to route to these subnets in config->networking->advanced->routing.<br />
<br />
<br />
==Is it possible to use DHCP without enabling NAT?==<br />
<br />
Yes, DHCP can be enabled if NAT is disabled. The DHCP start and end address range must fall into the network that you specify in the Network Configuration page. See [[DHCP Server|DHCP Server]].<br />
<br />
<br />
==Is it possible to serve DHCP on multiple interfaces?==<br />
<br />
Yes, just configure the DHCP settings on the appropriate [[Interfaces]].<br />
<br />
<br />
==Does Untangle support dual WAN or WAN failover?==<br />
<br />
Yes! Simply configure the appropriate [[Interfaces|interfaces]] as WANs, and install [[WAN Balancer]] for Load Balancing, and [[WAN Failover]] for failover.<br />
<br />
<br />
==Does Untangle Server use [http://en.wikipedia.org/wiki/Bandwidth_throttling bandwidth throttling]?==<br />
<br />
No. The Untangle Server uses Application Control Lite and Web Filter to solve the problem of network congestion resulting from a few users consuming more resources. [[QoS|QoS]] offers bandwidth management at the IP level.<br />
<br />
<br />
==My network is extremely slow and some pages won't load. Why?==<br />
<br />
Some internet connections have a sub-1500 [http://en.wikipedia.org/wiki/Maximum_transmission_unit MTU] but don't support automatic MTU path discovery. It is worth a try to manually change MTU on the config->interfaces->edit page to something lower, 1492 or even 1450, to see if it has any effect. You must be in advanced mode to change this setting. This is more common with PPPoE connections. It is suggested that if this does not solve the issue you return MTU to the default setting.<br />
<br />
<br />
==Can I use OpenDNS with Untangle?==<br />
<br />
Sure. Simply change your external interface's settings to use OpenDNS's servers as a DNS server.<br />
