DSL-522T ADSL Router User Guide
Additional settings for Static IP Address connections:
| Static IP Parameters | Description |
|
|
|
| Connection Type | This specifies the connection type and the encapsulation method used for |
|
| your Static IP Address connection. The options available are Bridged IP |
|
| LLC, Bridged IP |
| IP Address | This is the permanent global IP address for your account. This is the |
|
| address that is visible outside your private network. Get this from your ISP. |
| Subnet Mask | This is the Subnet mask for the WAN interface. Get this from your ISP. |
| Gateway Address | This is the IP address of your ISP’s Gateway router. It provides the |
|
| connection to the Router for IP routed traffic that is outside your ISP’s |
|
| network. That is, this will be the primary connection from the Router to most |
|
| of the Internet. Get this IP address from your ISP. |
| ARP Server Address | This is not required for all IPoA connections. Check with your ISP for an |
| (IPoA connection only) | ARP server IP address if this is necessary for your IPoA connection. |
|
| |
| Primary DNS Address | This is the IP address of the first choice for Domain Name Service (DNS) |
|
| used to match the named URL web address used by most browsers with |
|
| the actual global IP address used for a web server. Usually this will be a |
|
| server owned by the ISP. Get this IP address from your ISP. |
| Secondary DNS Address | This is the second choice for a DNS server. Get this IP address from your |
|
| ISP. |
| MTU | The Maximum Transmission Unit size may be changed if you want to |
|
| optimize efficiency for uploading data through the WAN interface. The |
|
| default setting (1400 bytes) should be suitable for most users. Some user |
|
| may want to adjust the setting to optimize performance for wireless traffic or |
|
| when low latency is desired (such as with Internet gaming). It is highly |
|
| recommended that the user research how adjusting the MTU may affect |
|
| network traffic for better or worse. |
| NAT | Network Address Translation may be enabled or disabled with the pull- |
|
| down menu. Keep in mind that disabling NAT allows on a single computer |
|
| to be used for Internet access through the Router. NAT is enabled and |
|
| disabled for the Router on all connections (i.e. Pvc0 – Pvc7) if your Router |
|
| is set up for multiple virtual connections. |
| Firewall | Use this to universally enable or disable the Firewall and Filter features |
|
| available in the Router. If you disable this you will not be able to configure |
|
| settings in the Firewall Configuration window or the Filters window in the |
|
| Advanced directory. |
