Strange problem after Upgrading to .17

RouterOS General
1

Hi,

Had a bad weekend and one RB burned out. Replaced it with a new one and put on a .17 firmware. This router has 2 wireless CM9 cards, one operating an Omni with users connectiong to it, and the other one dows a WDS link. Problem is like this:

Site 1: RB532, 2.9.17 2 x CM9. 1 AP and 1 WDS link (172.16.10.1) Internet Gateway
Site 2: RB532, 2.9.13 2 x CM9. 1 AP and 1 WDS link (172.16.10.3)

Wireless users on the other side (site 2) of the WDS link can ping everything connected to each AP. From Site 2 (172.16.10.3) Router i can ping everything. Users connected to Site2 (172.16.10.3) can ping everything Except 172.16.10.1 (Internet gateway). This means they cannot get to the Internet. Client units are Linksys WRT54G’s in client mode.

I see the ARP entries are ok, but no L2 or IP traffic from Site2’s wireless users are getting through to 172.16.10.1. Only way to get around this is to make 172.16.10.3 default gw for these users. However Site2 users can ping clients on Site1… What is going on here? Everything worked when 2.9.13 was on the Site1 router…

I got something similar:

something still are trying to find your (172.16.10.1) Internet Gateway by old MAC address of the previus router!! You need to clear the arp tables or replace your routers MAC with the one from the last router!

Arp entries on Client equiptment are ok. Arp on .3 is ok, otherwise i couldnt ping .1 from .3
