LANcache (Steam, Riot, others nginx proxy)

RouterOS General
1

For those that might run RouterBoard-powered LAN parties, I thought I would share my Routerboard DNS setup for using LANcache to cache Steam and Riot since it took me a bit of trial and error to figure out:

add address=192.168.100.30 name="lancache-steam" ttl=3600s comment="LANcache Steam Proxy/Cache"
add address=192.168.100.30 name="cs.steampowered.com" ttl=3600s comment="LANcache Steam Proxy/Cache"
add address=192.168.100.30 name=".*.cs.steampowered.com\$" ttl=3600s comment="LANcache Steam Proxy/Cache"

add address=192.168.100.30 name="clientconfig.akamai.steamstatic.com" ttl=3600s comment="LANcache Steam Proxy/Cache"

add address=192.168.100.31 name="lancache-riot" ttl=3600s comment="LANcache Riot Proxy/Cache"
add address=192.168.100.31 name="l3cdn.riotgames.com" ttl=3600s comment="LANcache Riot Proxy/Cache"

The actual proxy is running off a Linux server with a setup similar to what LANcache configures.

I stumbled upon this today trying to do the same thing but this is now out of date. Taking the domains listed here for steam and changing the wildcards to regex I managed to get it working (this is for Steam only).


/ip dns static
add address=YOUR_IP_ADDRESS comment="LANcache Steam Proxy/Cache" name=\
    lancache-steam

add address=YOUR_IP_ADDRESS regexp="^(.*\\.)\?steampowered\\.com\$"
add address=YOUR_IP_ADDRESS regexp=\
    "^(.*\\.)\?hsar\\.steampowered\\.com\\.edgesuite\\.net\$"
add address=YOUR_IP_ADDRESS regexp="^(.*\\.)\?steamcontent\\.com\$"
add address=YOUR_IP_ADDRESS regexp="^(.*\\.)\?edgecast\\.steamstatic\\.com\$"
add address=YOUR_IP_ADDRESS regexp="^(.*\\.)\?akamai\\.steamstatic\\.com\$"
add address=YOUR_IP_ADDRESS regexp=\
    "^(.*\\.)\?steam-content-dnld-1\\.apac-1-cdn\\.cqloud\\.com\$"

Just replace all instances of YOUR_IP_ADDRESS with the IP address of your steam cache server. I have also attached these commands as an RSC file if that is easier.
