881W Address Assignment Issues

[garland123]

Hi Community.

Currently trying to set up a 881W with the following set up

We have 5 Public IP's e.g xxx.xxx.xxx.14 - .18

The 881W is sat on .14 - no problems.

DHCP pool is set 10.10.10.2 to 10.10.10.150

IP range 151 - 254 will be used for us to manual allocate the 5 IP address - probably wont change either

So lets say

10.10.10.151   >>     xxx.xxx.xxx.14   

10.10.10.152   >>     xxx.xxx.xxx.15

10.10.10.153   >>     xxx.xxx.xxx.16

10.10.10.154   >>     xxx.xxx.xxx.17

10.10.10.155   >>     xxx.xxx.xxx.18

At the current time we have NAT'ed the traffic we need for our software, eg. from an external IP to internal IP (port 9000 and 9001) - this works well and as normal.

However we want to be able to RDP into that specific (external IP address) from outside the office. I have tried NAT'ing port 3389 for RDP connections.

Also on the client PC the "whats my IP" is that of the router (fixed).

Am I missing something very obvious?

Could you share the internal IP of the machine that you are trying to RDP to?

Also, share the NAT statement for this machine.

When you try to connect to the Public IP for this machine, do you see any hits in the NAT translation table?

show ip nat tran | in :3389

Do you see any entries in here for the public IP that you just tried to connect?

Make sure that the gateway of that machine (inside) points to this router's NAT inside interface?

Can you ping the inside IP of that machine?

Can you RDP into that machine from a diffrent machine in the same vlan (inside)?

Regards,

Hi Amit

Apologies for delay in response.

Seems I over complicated things initially. Should have handled the port rules through the firewall rather than NAT.

Still have an issues, where devices inside our now (192.168.1.xxx) internal range, cannot talk to devices on the same VLAN, via their external IP address, but work fine on 192 address. Any thoughts on this?
