example i have 3 cyber with 22 PC in total, and 20 home user customers for internet, and the satellite give burst to 1024 kbps
i have squid (webproxy Mikrotik), and Dns cache.
but bercafull, with Cache dns, i have to much trafic, (cyber), to Dns, and my Dns go to full quickly.
i change this parameter, /ip dns cache set max-cache-limit=30m
by default in Mk is 1w = 1 week for TTL, i was changed to 30 minutes.
the reason, is because, one time, try use the internet, and the browser need time for open a website, but when use FTP go very fast mmmmm
i see in dns cache, is full, and take time for search the domain for give the IP or go to other dns.
other symptons is the CPU go to high example to 40%, now is 0% to 4%
now my service go very fast,
my satellite service is share service and my CIR is 512kbps and MIR to 2mbps (only in the night 11:30 am to go). the rate go to 800 kbps in the day to little up to 1024 kbps
I am on a satellite connection to the internet and my average ping to yahoo ranges from 800+ms to a max of 950.
My three questions are as follows:
Whats the best value for the MTU for the lan card connected to the Linkstar box? (its currently at 1500)
Also since i am on a satellite connection my dns can take half a second to a second to resolve. So i would love to make the dns cache in routeros be first before going out and doing the dns from the ISP.
Another thing would be to have the web proxy work its magic so (just like the dns) i can get the cached stuff first.
Any help on how to do these things would be greatly appreciated.
