2017年2月6日 · By default docker doesn't support this capability. But you can pass below parameter while launching docker container to support Linux capability: --cap-add Add Linux capabilities --cap-drop Drop Linux capabilities For Network capability like iptables, ebtables etc. you have to add NET_ADMIN capability like: docker run -it --cap-add=NET_ADMIN ubuntu bash if ebtables package not installed then ...

Both ebtables and iptables INPUT chains are only run on packets destined for the local machine, NOT on packets that are being forwarded (either at layer 2 or layer 3). Changing from using the INPUT chain to using the PREROUTING chain (especially in ebtables will likely fix your issue.

2022年3月2日 · I ran into this same situation. it appears that broute isn't built into the current version of ebtables. use the command ebtables-legacy with the same options (i am using accept as opposed to drop) it will add the rule to the broute table and function as expected

I'm trying to drop a MAC address on a node in my network. Now, I tried two tools iptables and ebtables, but both attempts failed: iptables -A INPUT -m mac --mac-source 00:0F:EA:91:04:08 -j DROP

2010年11月25日 · Is it possible to use ebtables to filter traffic by MAC-addresses on simple ethernet interface, without bridging?

In most cases, this other IP is on a separate server. This all worked perfectly until we installed bridge-utils and changed to using a bridge br0 instead of eth0 as the interface. The reason we have converted to using a bridge interface is to gain …

2016年10月20日 · I have tried the following command iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 192.168.2.75:80, which does not work and should be broader. Also, I am trying to redirect traffic to the nginx httpd on port 80, not to the squid server. This is done to show on-screen instructions on how to config the proxy since the squid-server is being run as a non-transparent proxy.

2012年8月13日 · I want to execute a shell script when particular ebtables rules match. The Script should get the MAC address of the client and the interface in which the client is connected. how can I achieve this?.

2015年1月13日 · Having done some research, it seems like ebtables is the tool I need, but configuring it seems to need more knowledge of DHCP and networking than I have! From reading a few ebtables tutorials, I think I need to allow traffic on ports 67 and 68 (I believe these are the only ports used for DHCP?) and block all other traffic.

2018年9月20日 · Of course, iptables now provides its own ebtables implementation, but that implementation evidently does not include a manpage and does not seem to support all the options that the old ebtables does. (For now, I've solved this problem by downgrading iptables and reinstalling ebtables.) So, I'm looking for either of these things: 1.
