Unable to change WAN IP

RouterOS General
1

Hello,

I have an RB3011 that will not allow me to change the WAN IP. I’m trying not to factory reset and re configure as this router is in a production site, that is managed remotely.

I’ve tried using the “QuickSet” feature in Winbox to change the WAN IP. The Quickset feature shows the IP as changed, but when I check the route table, it is not. I’m also unable to delete the auto created static rule, or edit it.

I’m trying to move from the .101 address, to the .102 address.

I’ve also tried to downgrade the OS to the long term version 6.45.9, and then change the WAN IP.

Unsuccessful as well.

Never use quickset after you set whatever outside the quickset menu. It is about to break something in your configuration.

It might be easier for you to change a diaper, but sounds like your router is stinky too.

Seriously, what do you mean change WANIP
For example my ISP provides my WANIP, its not up to me to change.

You are probably stinkman but sometimes you can change the ether1 MAC address and reboot your cable modem and get a different IP.

Maybe he is free to change his wan ip… None could know.

I’m sorry your ISP doesn’t allow you to have a static WAN IP.

At this site (and many others that we manage) we have public static IP’s (Due to the software we connect these routers back to). Normally in a block of 5 (/29), so we have a total of 5 static IP’s that we can use. We had an issue with one specific IP in that block, and needed to change away from it. (There was a device that was infected with malware and was being used as a mail relay, so the IP of the center was blacklisted.) This caused a reCAPTCHA to show on EVERY website ANY computer on the LAN tried to access.

I was able to reinstate the router from a backup taken 2 weeks ago, and then change the WAN IP of the primary ISP circuit to a different one in the block of 5 that we have, and now the reCAPTCHA’s are gone, the reputation of this IP is clean, and everything is working properly.

This has been resolved. Thanks for everyone’s help.

You are correct jarda. We have a block of 5 public static IP addresses we can use. (I manage networks for Shared/Coworking spaces) Some get rented to tenants VPN routers, or we use them in the event that we have an IP that’s blacklisted due to bad reputation.

Nobody needs more than 1 IP that’s why we have NAT don’t waste.

No, it’s slightly different. We still have to suffer with NAT, because there are people who think that nobody needs more than 1 IP.

That doesn’t work in a commercial office space setup. For security reasons when dealing with the financial sector. Their industry standard requires dedicated static IP’s for the VPN devices, among a few other security standards we have to comply with. We’re not being wasteful, were following regulations. I’m sorry your unable to understand things like this, but thanks for your input either way.

It’s to bad those people just don’t understand more then what’s right in front of them..

Thankfully we are able to do this with multiple static IP’s, and not have to NAT everything. (we do have plenty of devices that are behind a NAT on a few of the subnets behind the router)
