Otherwise choose ‘IP Routing’.

a. For PPPoE, set ‘Sent Authentication Type’ as necessary. Only your

provider can tell you the correct type. Your provider may refer to this as

the “Authentication Method”. If your provider does not require

authentication for PPPoE, choose ‘None’.

b. For PPPoE, set ‘Sent Username’ and ‘Sent Password’ as necessary.

Only your provider can tell the correct settings.

4) Set ‘Address Type’ as necessary. Choose ‘Negotiated’ or ‘DHCP’ if your provider

will dynamically assign you an address. Choose ‘Static’ if your provider has given you a

Public IP address that will never change, and the provider is not going to dynamically

assign that address.

a. For Static, enter the appropriate ‘IP Address’ and ‘Subnet Mask’ as

given to you by your ISP.

b. For Static, enter the appropriate ‘Default Gateway’. Your provider may

refer this to as the ‘ISPs Address’.

c. For Negotiated, check the ‘Default Route’ option.

5) If you have multiple Public IP Addresses that you would like to use, add them as

Secondary IP Addresses. Click “Add a New Secondary IP Address” and enter the

settings for a single secondary address. Repeat for additional addresses.

6) Click ‘Apply’

Configuring the Private Interface:

If you are establishing a new private network, or you do not have a preference for the IP

Subnet used in your Private network, skip to “Configuring the Firewall and NAT”.

7) Click ‘Private Interface’.

all traffic. This will be referenced by the NAT rule in the Private Policy-Class.

19)Type ‘permit ip any’ to match all traffic.

20)Type ‘exit’ to exit the access list configuration.

21)Type ‘ip policy-class Private’ to create the Private Policy-Class. This is referenced

in the configuration of the private interface with ‘access-policy Private’.

22)The next statement will define what Public address to use in the NAT.

a. For non-PPP connections, where you entered the public IP Address on the

Public Ethernet Interface, type ‘nat source list MATCHALL interface

eth 0/1 overload’.

b. For PPP connections, where you entered the public IP Address on the PPP

interface, type ‘nat source list MATCHALL interface ppp 1 overload’.

23)Type ‘exit’ to exit the Private policy class configuration.

24)Type ‘ip policy-class Public’ to create the Public Policy class. This policy class will

remain empty. An empty policy class denies the initiating of sessions from that

Testing Internet Access

Before testing Internet Access, verify the following information:

•Your computer’s IP Address should be in the same IP Subnet as the NetVanta’s

Private Interface

•Your computer’s default gateway should be the NetVanta’s Private IP Address.

•Your computer’s DNS settings should be set to those given by your ISP.

You should now be able to access the Internet. If you are unable to do so, please reset

your NetVanta 2054, using the instructions in “Resetting the NetVanta 2054” and re-

execute this document. If you are still unable to do so, follow these instructions to pre-

pare for calling your ISPs technical support.

1) Attempt to ping the NetVanta’s Private IP

2) Attempt to ping the ISPs Gateway IP Address from your computer.

3) If that works, attempt to ping 4.2.2.2 (a root internet server).

If you are able to ping 4.2.2.2, double check your computer’s DNS settings.

If you are able to ping your ISPs gateway, but unable to ping 4.2.2.2, please call your ISP

and report a network outage.

If you are unable to ping your ISPs gateway, please verify with your ISP that your

Internet Service has been activated, and then call AdTran Tech. Support.

If you are unable to ping the NetVanta’s Private IP, please Reset the NetVanta, and reuse

this guide. If you are still unable to ping the NetVanta, please call AdTran Tech. Support.
