用緊兩個router，但係想將o的電腦係set 做同一個network

Question

屋企而家用緊兩個router，router A同 router b, router a 係直接由hkbn 條線入的，而 router b 係駁o係 router a 度囉 ip 俾其他人上網的。
router a 派三個 ip 出去， 192.168.1.2(主電腦) , 192.168.1.3(次電腦) , 192.168.1.4

router b 就囉 192.168.1.4 之後再派俾另外幾部電腦用。呢o的電腦係囉 router b 派o既192.168.11.xxx

想問下，有冇方法可以將所有電腦 set 做同一個 network 的呀﹖
即係我想是一部電腦開 share folder，所以電腦都可以睇到。
而家主電腦開share，只係得次電腦睇到，其他睇唔到咁。
同埋，可以玩o的可以intranet一齊玩o既game。我想是旦一個host game 都可以 join 到。

請大家教一教

Answer 1

你想用router b 做 switch ? 那不如買一個switch方便.
router可以set 做 bridge 嗎?
沒有這功能的話
或者你試下用 VPN , 用vpn就可以經過router b 來share file了

Answer 2

What is your reason for using 2 routers?

If your reason is keep separate secure network, then you're current connection method is correct. But only 192.168.11.xxx network is protected from 192.168.1.x network, and user on 192.168.11.xxx network can still hack 192.168.1.x network due to Router B act as firewall for protection.

If your reason is to have more network port, then you you should connect your LAN cable from Router A switch port to Router B switch port. Use the uplink port on Router B or use a cross-over LAN cable to connect the two routers.
Only use DHCP from Router A and disable Router B DHCP. This setup allow all machines connection to share same network.

Windows file share does not work across router/firewall unless all the required ports are properly opened and forwarded. Reconsider your need and setup all machines properly in one single network or keep your separate networks.

咁奇怪？你Router A同Router B的IP會唔甘大分別？
通常駁法都係將Router B變做Switch，Router B唔會派IP架喎！
而且，祇要將Router B的DHCP功能關閉，就已經在同一網絡啦喎。
