Hi,all:
        recently,i installed openwrt (version:attitude adjustment r33444) to my router(tp-link 741nd v4),and set lan ip to 192.168.1.1 and wan ip to 192.168.2.1.When i ping 192.168.2.1 and 192.168.1.1 from wan direction ,it could both be successful!!!Also i ping 192.168.2.1 and 192.168.1.1 from lan1 direction,but i found that i can only ping 192.168.2.1 successfully.Other ports(lan2\lan3\lan4) are normal, and i can sure i haven't do anything else settings.
        It seems like wan port and lan1 port have switched their functions.Anyone else can give help?Thanks!!!
