Configuring Router for Multiple IPs

[JennyGW]

Hi all,

I currently have a single fixed IP. I host my own servers, life is good.

I would like to add more IPs so that I can route traffic between IPs and not just port forwarding. Eg, I would like a development server and a live server.

All of the hardware is in place and has been working very nicely for some time.

My ISP, Zen Internet, does not support router configuration for port forwarding or multiple IPs, but they will rent me an IP block.

I had one go at this and it failed because Zen would not support this configuration and I didn’t know how.

As a sample, this is the IP information they gave me last time.

IP addresses: 77.104.175.104 - 77.104.175.111
Subnet mask: 255.255.255.248
Subnet in slash notation: 77.104.175.104/29
Network address: 77.104.175.104
Broadcast address: 77.104.175.111
Router address: 77.104.175.110
Number of IP addresses usable by your hosts: 5

DSL connection

IPv6 address: 2a02:8011:d017:8262::1/64, valid: 258028/171628s
IPv6 prefix: 2a02:8012:8a3c::/48, valid: 258010/171610s
DNS servers used
212.23.3.100 (currently used for standard queries)
212.23.6.100
2a02:8010:6::212:23:6:100
2a02:8010:6::212:23:3:100

As far as I can see this should be fairly straight forward process. I just need a step through for what goes where.

Is there anyone who could please help me with this?

Many thanks in advance,
Jenny

So you are after more WAN IP addresses, that is, outward facing, public IP’s?

Not sure of Zen’s full range of services but they are an Internet Service Provider mainly so probably don’t do what you are after.
I believe you’ll want the services of a domain hosting mob. They can offer managed or self-managed Virtual Machines.

Hi Bruce,
Zen provide me with the option for multiple WAN IP addresses.
i already have the servers.
You have experience configuring subnets on routers?

[Bruce]

Sadly no.
The 254 addresses available are all I have needed.
I have run out of IP’s but that was because the IP release figure was set to days rather than hours.
Changed that to 4 hours and haven’t run out since.

I’ll tag some other members in case they have skin in the game - @PeterOz @georgeks @Pyro @Bastet @phillpower2 @xrobwx71 @Malnutrition

Not something I’ve looked into tbh.

Hi Bruce,
Thanks for your response!

I think you are referring to 254 internal IP addresses which can be allocated automatically via a DHCP server. Often an ISPs router is used for this.
This is not relevant to the external WAN IPs.

Domain hosting is something else altogether.
ISPs do hold IP block ranges that they sell (rent) to customers.

Have a look at this.
All static IP’s are to be entered directly on the computers involved.
