First post here and first days using Openwrt, so definitely a newby... bear with me
I've been reading quite a few posts here in the forum and all the guides in the website User guides section in order to set my old Alice Gate router running openwrt as a dumb switch/AP. After many tests and resets I managed to get it working; my configuration is as follows:
- Static IP 192.168.2.1, subnet 255.255.255.0, gateway & DNS 192.168.1.1 (main modem/router)
- DHCP disabled, all IPv6 options disabled
- All ports untagged under the same VLAN1
- Access point with same SSID/key as primary modem, in the LAN network
My doubts are now:
- following the DumbAP guide it is clearly stated to disable firewall, dnsmasq and odhcpd in the startup page, but following these instructions I wasn't able to reach neither LuCi interface nor to connect via SSH, and a reset was needed... my understanding is that IPv4 and IPv6 are now provided by the main router, and in fact I cannot connect to Openwrt without a static IP, and that Openwrt is on a separate subnet (.2.x), thus not "interfering" with my router DHSC. I'd love to understand if what I've done is correct, if having the firewall and the other services running while acting as AP is ok, and if openwrt is "playing a role" in the network now or if it's an invisible switch.
- reading the Bridge guide seems like realyd is needed to access devices connected to the main router from ones under the openwrt, and viceversa, but I've found that I can still see and exchange files even without that package. Would like to understand why is that possible.
- moreover - and this could be a pretty stupid question, I know - I'm wondering if having the router on a different subnet will prevent me from using the USB port to run a print server - or whatever.
Thanks, for the help and the pacience!
