Hi,
I am using openwrt as secondary router. here i am have provided it a static local ip and dhcp disable. I am able to browse it on local and using its attached network drive too but transmission is not working.
Certainly. You have come into this forum and demanded - "do the needful" - that complete strangers, all of whom are volunteers, help you. But you have not provided any detail about your configuration which will help the members of this forum to help you.
No-one here is telepathic. If you can provide details of your router's configuration, as well as your network topology, along with details of all the troubleshooting steps you have attempted so far with their results, it will improve the chances of someone here being able to help you.
Actually, i am using wifi from ISP router, i have another router with openwrt. If i connect it with lan from ISP router through internet port,it will create a separate network. I don't want to create two network I want only single network so I can use transmission and attached storage.
For example, my ISP router on 192.168.0.1 and openwrt through internet 192.168.1.1, here transmission is working perfectly but not able to access attached drive on ISP network.
For now i configured openwrt, provide it a static IP 192.168.0.2 and DHCP configuration off. Now both are on same network, i am able to access openwrt attached storage and luci web, but transmission is not working.
I want to make working both, transmission and attached storage on a single network.
From your description, it sounds as if you are connecting the two routers with a cable ("internet port").
If so, then it also sounds like you're almost there.
When you gave OpenWRT a static IP address 192.168.0.2, did you also assign a gateway/default route? By default, the LAN interface does not need a gateway, because in normal use as a router it is the gateway. However, the way you're using it, OpenWRT is simply one more device on your ISP router's network (192.168.0.0/24). And, in that case, OpenWRT needs to know how to get to the Internet; i.e. a gateway or a default route.
What are the contents of /etc/config/network from OpenWRT?
