Kenny83's questions

I have two routers that are interconnected via Cat5 cable: a TP-Link Archer C7 and an old Netgear V7610. I am trying to create two subnets on the same LAN, and maintain communication between all nodes, regardless of which router they're connected to.

The Archer C7 is running OpenWRT and has its 2.4GHz WiFi radio disabled, while the Netgear V7610 is running proprietary firmware from my ISP and has its 5GHz radio disabled. All of this is to workaround the inability of the C7 to use both radios simultaneously. I have been unable to rectify this core issue, since it defies belief by any OpenWRT experts that I've spoken to about it. See this OpenWRT forums thread for more information on that.

I would simply scrap the V7610 and run everything through the C7 on 5GHz if I didn't have some older devices that don't support the newer WiFi standards. So this is the only solution that I can think of, besides running Cat5 all over the house, which would be too costly in terms of both time and money.

I have read through the following resources but am still confused:

Creating a link between two OpenVPN subnets

Communication between two different network id

https://openwrt.org/docs/guide-user/network/routes_configuration

The last one in particular is the first thing that I tried, i.e. setting up a static route from the C7 to the V7610 like so:

192.168.1.0 is my C7's network address, and the V7610 (192.168.2.0) is connected to it through 192.168.1.254. The cable that connects them runs between the WAN port of the V7610 and a LAN port of the C7.

All of this works great except for the issue mentioned in the title. For example, 192.168.1.2 can't communicate with 192.168.2.2. Connectivity between all nodes and the Internet is working fine.

So after that lengthy introduction (sorry!) here are my actual questions:

1. Why does the static route on the C7 not work?
2. Would disabling DHCP on one router or both fix this?
3. How else may I be able to fix this frustrating and baffling issue?

I know this question has been posted many times, but even with the help of those answers, I can't seem to figure this out.

I'm a freelance web developer and just started maintaining and administering an existing vBulletin forum site. The site has hundreds of thousands of members and millions of posts already on it, so to avoid catastrophe, I thought I should setup a dev environment to work off of rather than mucking around with the real production site.

But being a complete newbie to nginx (the server used on production), I can't figure out why I'm constantly getting the error mentioned in the title.

Here's the site's config file:

server {
    listen   80; ## listen for ipv4; this line is default and implied

    root /home/bolt/domains/bolt.cd/public_html;
    index forum.php index.html;

    # Make site accessible from http://localhost/
    server_name bolt.cd www.bolt.cd;

    location / {
    #    try_files $uri $uri/ /index.php;
    }

    location /board/ {
        rewrite ^/board/((urllist|sitemap_).*\.(xml|txt)(\.gz)?)$ /board/vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 last;
        try_files $uri $uri/ /board/vbseo.php?$args;
        access_log off;
    }

    location /board/vbseo/(packages|vb|includes|resources/html|resources/xml)/ {
        allow 127.0.0.1;
        deny all;
    }

#   location ~ /board/(.*\.php)$ {
#       rewrite ^/board/(.*)$ /board/vbseo.php last;
#   }

    location /board/(neverfind-72891|modareaz-3782|install)/ {
        auth_basic "Private";
        auth_basic_user_file /home/bolt/.htpasswd;
    }

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index forum.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param QUERY_STRING $query_string;
        fastcgi_param REQUEST_METHOD $request_method;
        fastcgi_param CONTENT_TYPE $content_type;
        fastcgi_param CONTENT_LENGTH $content_length;
        fastcgi_intercept_errors on;
        fastcgi_ignore_client_abort off;
        fastcgi_connect_timeout 60;
        fastcgi_send_timeout 180;
        fastcgi_read_timeout 180;
        fastcgi_buffers 256 16k;
        fastcgi_buffer_size 32k;
        fastcgi_temp_file_write_size 256k;
    }

    location = /robots.txt { access_log off; log_not_found off; }
    location = /favicon.ico { access_log off; log_not_found off; }
    location ~ /\. { deny all; }
}

And every request to {root url}/board returns a 500 error page, with the following logged in /var/log/nginx/error.log:

2016/10/26 07:31:37 [error] 4760#0: *4 rewrite or internal redirection cycle while internally redirecting to "/index.html", client: 10.0.2.2, server: localhost, request: "GET /favicon.ico HTTP/1.1", host: "localhost:6544", referrer: "http://localhost:6544/board"

I'm pretty sure I've installed PHP-FPM correctly, although it could be a problem with that, or with the php.ini config file, but I'm pretty certain the error is somewhere in that nginx config file.

MTIA for any help with this frustrating issue! :-)
