Multiple IP Address Configuration, NAT Help using a NV6355

Jump to solution

Hello,

I am trying to configure a NV6355 for Multiple IP Address usage. Let me explain what I am hoping to accomplish.

1. Internet is coming in on a fiber connection, VLAN tagged 61. I am using an SFP module on GIG 0/2. The IP's are gateway: X.X.X.241, NV6355: X.X.X.242, the block is X.X.X.225 - X.X.X.230. All the IP's are on the same subnet.

2. All the ports are set to trunked. VLAN 61 has been created and assigned the IP address X.X.X.242. An IP route 0.0.0.0 0.0.0.0 X.X.X.241 has been created, and internet access is present on all ports after running the firewall wizard.

3. The block of IP addresses will be used on other public devices that will be plugged into the 6355. I can add the block as secondary IP address's on the VLAN interface, and ping them all. When I remove the block and add an IP to a public device, the ping times out.

So I am hoping that there is a way to configure the 6355 for the routing of the block of IP address's to the public devices plugged into the unit. I have tried to configure encapsulation 802.1q and sub-interface on GIG 0/2, but get an error stating "could not perform operation."

If there is not a method of doing this, can anyone recommend an Adtran router that will do this with a fiber connection?

Thanks,

Jack

Re: Multiple IP Address Configuration, NAT Help using a NV6355

Ta5000guy77,

Thanks for posting!  If I understand this correctly, it sounds like you have just a completely separate /29 subnet you can use.  Generally I would recommend that you create a new VLAN, VLAN 100 for example, and assign one public IP address from that range to the VLAN interface.  So at this point we have VLAN 100 created with IP address x.x.x.225.  Next, I would assign a few ethernet interfaces as access ports (not trunk ports) on VLAN 100.  For example, if you have three device which need public IP addresses, you could change ethernet ports 22,23, and 24 to access ports on VLAN 100.

(config)#interface vlan 100

(config-intf-vlan 100)#ip address x.x.x.225 255.255.255.248

(config-intf-vlan 100)#no shutdown

(config)#interface range eth 0/22-24

(config-eth 0/22-24)#switchport mode access

(config-eth 0/22-24)#switchport access vlan 100

Now you should be able to give devices on those ports one of the available public IP addresses and set its default gateway to the Adtran unit's x.x.x.225 IP address.  Your next step will be to make sure the firewall is allowing traffic to and from this subnet.  The following guide goes over setting up a DMZ.
