    Going from your LAN rules, you should be able to access your OPT network simply from

    IPv4 *    LAN net    *    *    *    *    none         Default allow LAN to any rule

    How are you testing whether you are able to access it? The rule

    allow IPv4+6 TCP/UDP    HOTSPOT net    *    LAN net    *    *    none         Allow LAN to HOTSPOT

    in your OPT1 interface should not be in there if you want to block OPT1 traffic to LAN. Remember that firewall rules apply to incoming packets unless it's a floating outgoing rule. As it is set up now, the firewall should be passing traffic from LAN to OPT1, and vice versa. You likely have a problem elsewhere, most likely in either your testing methodology or your routing.

    Thanks for reply timthetortoise.

    ''Going from your LAN rules, you should be able to access your OPT network''
    That's the problem… I am able to go on 10.10.10.1 form LAN (desktop), but some how I can't access to my access point (10.10.10.4 access point IP) from LAN. There are no other rules there...

    '' in your OPT1 interface should not be in there if you want to block OPT1 traffic to LAN ''
    yes I want to block OPT1 to LAN.

    '' You likely have a problem elsewhere, most likely in either your testing methodology or your routing ''
    I am testing https://10.10.10.4 in browser to log in to my access point. also try http://10.10.10.4 but no luck
    If I use https://10.10.10.1 then pfsense log in page show up.

    If you need other info please let me know...Thanks

    Again, what is the default gateway on your access points? If it's not 10.10.10.1, they will not be able to communicate with your 192.168.1.x network.

    Pfsense box LAN interface is set to https
    OPT1 interface is set to https but on OPT1 interface the Captive Portal is set to http.

    Is this set up can cause this problem??

    Download nmap and do a port scan of the access point. Make sure HTTPS is actually showing up. If it's not, but other ports are and/or you can ping it without any special rules, you've got a problem not related to pfSense.

    Thanks for reply…run scan interface-any, scan method-tcp, (can't run scan method-SYN)
    also I set LAN & OPT1 both to http

    Running: /usr/local/bin/nmap  -sT '10.9.88.2'

    Starting Nmap 6.25 ( http://nmap.org ) at 2013-11-12 14:50 CST
    Nmap scan report for 10.9.88.2
    Host is up (0.0037s latency).
    Not shown: 998 closed ports
    PORT  STATE SERVICE

    So since port 443 isn't open, why would you be able to connect to HTTPS? Try to connect to http://10.10.10.4

    Unless you have settings on your client machine that you're not revealing, don't know what to tell you. Good luck with it.
