How to set up a network in OpenWRT?

Question

linux

Good evening everyone. I can not solve one problem, I hope you can help me. There is a virtual machine (VirtualBox), it has its own compiled OpenWrt x86 firmware with almost all the packages I need, except for iptables-mod-extra , I couldn’t include it in the assembly, because it simply isn’t there. Accordingly, the only option is to download on a running machine. The installation was carried out according to these instructions . I put the network bridge (if that). I fulfill all the requirements, and connect to it from the local network. It seems like everything is set up, but there is one thing. The opkg command does not work correctly. For example, I write opkg install iptables-mod-extra, and he answers

Collected errors:
 *opkg_intall_cmd: Cannot install package iptables-mod-extra.

Further interesting, the opkg install command writes to any package what I wrote above, only instead of iptables-mod-extra the name of another package. Then it turns out that the commands opkg list-installed and opkg list , which should show a list of all packages and installed ones, do not react at all, that is, nothing happens. And one more nuance. The ping command does not work properly. The command
ping yandex.ru
writes ping: bad adress 'yandex.ru'a to 77.88.55.66(yandex.ru) or 8.8.8.8(google.com) and responds normally and pings them, gets answers. On another forum I was told that the network is not configured correctly. But how to set up everyone was silent. Here I come to you.
Ps: iptables-mod-extra is needed for redsocks, so there is no way without it.

Answer 1

1. First, set up access to the Internet, if the domain name does not ping, then the DNS servers are not configured correctly.
2. The source of third-party packages must be configured specifically for your platform.
3. When the two initial steps are done, do opkg update to update the list of available packages.
4. Install the required package opkg install ....
There is also a second option, download the ready-made iptables-mod-extra you need, and install it from the folder where you downloaded it, for example opkg install /tmp/iptables-mod-extra.ipk but if there are dependencies, they must also be downloaded.
