I am using a RB1100 to route Internet from our service provider to our WISP customers. Port 1 on the RB1100 is hooked to the Internet. Ports 2 - 10 route it to various sector AP's and backhauls. I have a couple of customers that have static IP addresses. At times they are unable to access the Internet. From the browser they get a page not found message. They run small business servers so their e-mail and website doesn't work when this problem occurs. Both users use MikroTik equipment for the CPE's. I can log into their CPE's but can't ping anywhere on the internet, using the /tools/ping command. I have tried rebooting the RB1100 and all the backhaul's, AP's and CPE's inline but that doesn't fix anything either. The strange thing is if I go into to the Radius server and give them a different static IP address, or if I change the username and password on their CPE to something different, the Internet starts working. Problem with doing this is that they need their static IP address to not change. I have run a trace route from their CPE when this happens and it seems to die at the RB1100. If we just wait some time it will eventually cure itself. This may be a few hours to a day or two. Waiting in unacceptable as they are not able to work while this problem occurs. Has anyone encountered this problem before? If so what did you do to fix it? Not sure what to do next. The RB1100 is running v5.26 as is the backhaul, AP and CPE involved. Let me know if I need to provide anything else to help troubleshoot this problem.

Thanks .. Jay

I've never heard of such a problem ever! ..I would however love! to know the fix for your problem when you fix it

look for netmask/prefix issues in the firewall / NAT rules and/or dynamic firewall rules which add IPs to access-lists and/or multiple users trying to use the same IP address at those times and/or routing issues between the RB1100 and the various sector APs and backhauls.

When all of that fails, you might want to actually give us some details. Things such as:

What access method the static IP customers use to get their static IPs, pppoe, pptp, dhcp, hotspot, statically configured IPs on the customer equipment, whatever.

Gather up all of the IPs, Routes, Firewall Rules, Firewall Mangle Rules, Firewall NAT rules, Firewall Address-lists and a network diagram.

Traceroutes from the customer toward the Internet.

Traceroutes from outside the RB1100 (traceroute.org is helpful) toward the customer's IP.

Traceroutes from other locations on your network toward the customer's IP.

Traceroutes from the Customer toward other locations on your network other than the RB1100.

Then make a detailed help request.

By the time you gather the data, you will probably have your answer.

I need help in figuring out why one of my Internet customers with a static IP address doesn't have any Internet access while my others do. Below is the information, I hope, that was requested earlier. I have included a trace to and from the customer without Internet as well as to a customer that has Internet. Both have static IP addresses and are on the same AP/Backhaul/RB1100. If any more information is needed please let me know.

Thanks

WHY???!!! It only breaks troubleshooting. Of course, so does having routed hops without public IP spaces on the links. Burn a /30 on each backhaul which is visible to the customer/ someone troubleshooting connectivity to the customer. Life is too short for non-functional network addressing.

Nothing to do with our host IP ranges, looks okay.

So, "Allow List" is your only address list on any of the routers?

I don't see 63.97.254.0/24 in the "Allow List" how do you get traceroute responses?

We need the relevant information, like what I left above, for the other three routers which are involved. Anything that references an IP in the traceroutes.

In the below traceroutes, does 63.97.254.211 and 250 live on these MikroTiks from which you are running the trace?

Non-Internet Customer


Customers without a static IP address are given an address from a private IP pool

You need to follow the packet through each hop looking at the firewall/nat rules and comparing them to the source address of the customer's packet. There is something, most likely in your other routers, which is doing something with packets from your customer to {not your IP space}. The problem customer may be in a dynamic address list which is used in a firewall or nat rule. The RADIUS attributes may be hosed for the problem customer and creating dynamic firewall rules for them which block their traffic to the Internet. You showed us 5% of the relevant data.

I'm very busy at work. It may be another month before I get back into the forums to look at follow-up. If you do your part of the homework, someone else may have the patience to review the relevant info sooner.

Thanks for the help. Putting the subnet in the Allow List seemed to help.
