I'm trying to understand network bridging (not hardware but software implementation), but get some misunderstanding.
A network bridge connects two parts of a network together. For example my computer is connected to a local network throught eht0
and to the Internet throught wlan0
. To share the internet connection in the local network I need to connect wlan0
and eth0
by network bridge. But why my routing table is not giving the same result without network bridge? I have the internet access, hence the routing table contains entries, that all outward packets should be passed through wlan0
, hence packets that come from local network as well as generated by me should be passed through wlan0
.
- Where is my mistake?
- How does network bridge fits in routing table ideology?
@YLearn Thanks for pointing this out; I've tried to update the post to make it a bit more correct; Please edit it further if you feel it is warranted. – Darth Android – 2015-05-07T15:36:45.637
Much better. However, I would still adjust the statement "automatically forwarded with no modifications" as this is still incorrect, especially in the context of the original question. A frame that is received on eth0 is an 802.3 (Ethernet) frame, but the bridge will modify this so that it is sent out the wlan0 interface as an 802.11 frame and vice versa. While similar, they are two entirely different frame formats. – YLearn – 2015-05-07T17:30:45.210
