Lossing access to network - dns og IP nat issue
Update:
Found this error. still cannot find anything regarding this in the documentation.
Nov 30 08:25:00 debug dnrd Reach the maximum simultaneous Masquerading connections discarding DNS (id='29383',client-ip-address='10.x.x.x(200)
Now and then we are having issues with one of our VSC's. We have on msm760 and approx. fifty MSM460's. The VSC in queston is 802.1x with radius and the dhcp/dns settings is within the VSC. The problem seems to start when the number of wireless clients reaches above 200. I suspect it to be either an IP problem or a DNS issue, but cannot be sure as the logs only gives me the error below. I noticed an infomessage on the controller mentioned an ip or dns maskerade limit on the vsc, but the 760 manual does not tell me anything regarding this. Error received is listed below.
Nov 29 10:34:56 err iprulesmgr Cannot provide network access to user (nas-port='59',name='host/xxx-xxx-41.domain.local',calling-station-id='0C-60-76-47-D6-4D',framed-ip-address='10.0.123.123') due to internal error.
Any help would be greatly appreciated.

Re: Lossing access to network - dns og IP nat issue
Hello again,
Could you please do this action plan. And let me know if they resolve the issue.
SYMPTOM:Too many DNS request discarding messages in the unfiltered log.
Cause
CAUSE:Receiving DNS request discarding messages in the unfiltered log like following.
Jan 23 10:13:51.418 debug dnrd: Reach the maximum simultaneous Masquerading connections discarding DNS (id='29392',client-ip-address='10.10.4.131'). (200)
Jan 23 10:13:51.418 debug dnrd: Reach the maximum simultaneous Masquerading connections discarding DNS (id='41118',client-ip-address='10.10.4.131'). (200)
Jan 23 10:13:51.414 debug dnrd: Reach the maximum simultaneous Masquerading connections discarding DNS (id='34047',client-ip-address='10.10.4.131'). (200)
Jan 23 10:13:51.414 debug dnrd: Reach the maximum simultaneous Masquerading connections discarding DNS (id='11876',client-ip-address='10.10.4.118'). (200)
Answer/Solution / and action plan :
FIX: Following are the steps to overcome this.
- Take a backup of the current configuration of the controller.
- Open it with a notepad.
- Search for “max-user-connections”
- By default it is “max-user-connections = 200”. Please increase it to 1000 and save.
- Restore the ‘saved’ config file to controller.
NB:
Please note, that you will need to have a downtime to do this as this process requires the controller reboot.
Best regards,

Re: Lossing access to network - dns og IP nat issue
I have a controller with the same issue. I just changed the values and confirmed it's reflecting in the config but the syslog is still spamming this same error. Is there anything else I can try?
**EDIT: I was able to get the error to stop spamming after configuring the DNS server to the local ISPs addresses. Previously the unit had been on Google/Level 3 DNS.
