RB450G restarting when connecting ISP

RouterOS General

Hello guys. :smiley:
Thanks in advance for wasting precious time reading my question. I have a RB450, RouterOS v6.31, set to be a small FW company that has an average of 100 users simultaneously surfing the Internet.
Unfortunately it is restarting, as a single condition and for that I need to explain my scenario:

I use three interfaces of the equipment.

The interface 1 is my first ISP, call the ISP1, link ADSLv2 + with 90 Mb of Down and 30 PU. Dial-up connection PPPoe.

The interface 2 is my second ISP, ISP2 with 100 MB of Internet Down and 10 PU.

In my interface 5 is my local network, I call LAN.

Before you begin, I need to mention that this is my second conf what I do and that presents the same problem here in my structure. The first setting I left was pretty full and heavier than it is now. There was QOS rules, Mangle and scripts. But when we add this new ADSL link, had trouble climbing a PPPoE interface and only worked when I enabled TCP MSS Change on the ppp profiles. It would be suspicious because of PPPoe, I put a router in front of FW to turn this pppoe connection provider and released in the DMZ all connections to IP FW.

Unfortunately nothing. Keeps restarting.

Then went to my second configuration. I made it simpler, do not mangle, QOS anything. So much so that ISPs put my interfaces in brigder and Netwach do Failover. But the same thing happens when I turn on the ISP1 after an hour or less my RB restarts again. Unfortunately I can not a log that helps me in finding this problem. Luckily I managed to capture this error:

Interface, warning ether5-master: tx on loop interface (1)
Interface info Ether1-isp1 link down
Interface info Ether1 isp1 link-up (speed 100M, full duplex)

Note: Unfortunately my English is very bad, I’m not nation with the language and the fact that living in another country. Thank you for your attention and sorry guys.

Have you tried upgrading it to the latest Bugfix-only release (6.32.3 as of the time) making also sure 450 firmware is up to date? (check System > Routerboard)

Suerte!

Thank you for your attention Pukkita.
Test with two RB450, one was older version and at the time I changed from what it is now, was the youngest version. I will upgrade to version suggested. I will research how to update the firmware, one thing I’ve never done before.
I will have to wait until the end of the day for this. :frowning:. But my current firmware is 3.07, it seems he suggested I update the firmware to 3.24.
It’s a great suggestion! :slight_smile:

A good practice when a device is under suspect or mishebaving:

1.- Save a configuration export. open New terminal and issue:

/export file=OriginalConf

Open Files and drag and drop OriginalConf.rsc to your desktop to keep a copy.

2.- Upgrade to latest bugfix-only release, 6.32.3 as of this time. Download it, drag it over Winbox, reboot (http://download2.mikrotik.com/routeros/6.32.3/routeros-mipsbe-6.32.3.npk)

3.- Go to System > Routerboard, and upgrade to latest firmware (3.24 right now). reboot.

4.- Once rebooted, open a New Terminal and issue:

/system reset-configuration no-defaults=yes skip-backup=yes keep-users=yes run-after-reset=OriginalConf.rsc

If issues persist, next thing to do is a netinstall http://wiki.mikrotik.com/wiki/Manual:Netinstall

Did you have graphs enabled on any of those 450G?

Hello! I have graphs enabled in RB450. Did the procedures that passed me, tomorrow will check if the problem persists. I’ll let you know tomorrow if your suggestion solved my problem. Thank you.

I have found having graphing enabled (disk activity) + power outages to be a risk factor for routerboard NAND’s to become corrupted. Usually a netinstall fixes it.

Thank Pukkita. Update the firmware solved the problem. Two days ago it did not restart more. :smiley:

Estupendo! (Great!)
