Hello everybody is there any way to compress data send and received to and from my isp so i can decrease my monthly download and upload data capacity.cz i have a 256/1mbps with 5 gb monthly usage only.
10x
The person/sending server would have to do this with you.
YOu need both ends to work together to compress 
You need web caching & compression.
That will help lots to reduce your bandwidth quota.
can mikrotik compress data? and how?
look for ‘packing’
and maybe pptp compression? =)
and to configure it in mikrotik plz? i have Mikrotik 2.9.27.
best regards
