RB1100AHx4 Bridge

Hi,

I just bought a RB1100AHx4 and bridge all ports. Once I enabled 'Use IP Firewall' in bridge, no packets can pass through even though I didn't block anything. Any idea how or where I can start troubleshooting this? I've search everywhere and have no idea what's wrong. Thanks.

Re: [SOLVED] Strange problem, can't ping gateway.

It is not certain it is really locking it, when the provider uses Cisco equipment it can take quite long before it switches to a new MAC address because the ARP lifetime is quite long and the outgoing ARP does not learn from incoming ARP requests. So it could have been it started working when you l...

Re: Strange problem, can't ping gateway.

I can ping any other IP within the /25 except .1 which is the router at my ISP. May be your provider uses MAC locking. In such case you have to call provider and ask unblock new MAC (some providers allow this to do online. Sometime they charge additional costs for this ^). Or change ether1 RB2011 M...

Re: Strange problem, can't ping gateway.

You need to put ether1 and ether5 into the bridge, then assign the IP address to the bridge, not the port. For your information, and I did assign the IP to the bridge. The rest of the machine within the same subnet can access to RB2011 and vice versa except .1 which is the ISP gateway. Bridge1=Ethe...

Re: Strange problem, can't ping gateway.

Are you just using the RB2011 as a switch? or are you routing? Can you export the bridge and ethernet config? I'm not routing anything at the moment, I'm just using it as switch. [MikroTik] > /interface bridge print Flags: X - disabled, R - running 0 R ;;; defconf name="bridge" mtu=auto a...

[SOLVED] Strange problem, can't ping gateway.

Hi, I was using RB600A. Due to port limitation, I decided to change to replace it with RB2011iLS. I set public IP to 2xx.1xx.1xx.2/25 to ether1, GW 2xx.1xx.1xx.1 and the rest of the ports are slave switch and bridged. I can ping any other IP within the /25 except .1 which is the router at my ISP.

[Solved] OpenVPN Speed.

Hi,

I created openvpn from RB2011 to RB2011. I can get 8-10mbps using bandwidth test. But when I transfer files from windows to windows, the max speed I can get is around 2Mbps. Any idea? Thanks.

Re: RB750G stops responding

I've setup resource graph, everything is normal, no CPU spike etc. I am able to access to the router via winbox while the rest of the users were unable to access to internet for about 10-15secs.

Hi, I'm using Mikrotik RB750G, the problem is that when we are browsing the router will suddenly stops responding and after some time, it'll resume operation.

Re: Problems on running production server

Since you changed hardware, you have to troubleshoot one item at a time. Were you using the same version of RouterOS before? Have you tried disabling multi-cpu?

Block Internet access.

Hi,

I'm using hotspot to block Internet access for users in LAN, the problem is this also block external traffic from coming in. I need to bypass remote management port like VNC or RDP so that we can manage PC without internet access. Anyway to do this? Thanks.

Re: dropped tcp (syn) packets.

Is "allow-remote-request" set to yes on the DNS server? Are there any firewall filters that block that port?
Yes, "allow-remote-request" is set to yes.

By default that port is block, but I have rules that only allows my subnet to connect to Mikrotik.
