Hello, 

what are the IP addresses given to you ? I am just asking because the /30 usually implies only one useable IP address on your side.

Either way, you can either use static NAT or, if the (public) IP addresses need to be directly assigned to your end devices, use a bridge group.

Hello

You can use Network Translation to map the public IP addressing to individual inside hosts when applicable.

or

You can bridge the rtr to colapse the wan subnet into your lan network?

(I would suggest the first option would be more applicable?

Be happy to provide examples if required?

Hello,

which (block of) IP addresses did you get ?

Post the config of your router, and we can add the necessary bits and pieces...

[osaid suliebi]

Hello,

IP block : 213.6.82.34-38 / 255.255.255.248.

Another Question: Can i connect my device to LAN port in router and Assign to this device IP from range that i have??

If Yes, kindly post to me example, i will post my conf..

[Georg Pauwen]

Hello,

what is the IP address and mask assigned to the WAN interface ? Is that an address from that same range ?

Usable addresses are 33- 38, by the way.

[osaid suliebi]

Hello, 

WAN IP is 213.6.78.186 /255.255.255.252

Just i want to connect my device (DVR) to one of router LAN port and access directly to this device by using one of ip from range..

Thanks

Hello,

assign e.g. 213.6.82.33/29 to the LAN interface of your router, and then you can use any of the other addresses (34 thru 38) for your devices.

Hello,

Thanks Geroge,

Assigne 213.6.82.33/29 as gateway to device that connect to any LAN port of router??

in another word: Assigne 213.6.82.33/29 to VLAN1?(as you know vlan1 contains the 4 LAN ports of router)

Thanks Again for your help..

[Georg Pauwen]

Exactly. 213.6.82.33/29 to VLAN1.

Thanks you Dear, 

Please note i configured IP pool as below, is this needed and nessesary??

ip nat pool Paltel_Range 213.6.82.37 213.6.82.37 netmask 255.255.255.248

ip nat pool Paltel_Range_37 213.6.82.37 213.6.82.37 netmask 255.255.255.248

ip nat pool Paltel_Range_36 213.6.82.36 213.6.82.36 netmask 255.255.255.248

Hello,

you don't need these pools at all, since you are using public IP addresses. That said, do you have any other hosts in your network with private IP addresses ? If that is the case, you would need to NAT those, but not using a pool, but just an overload to the WAN interface...
