hii..

is that mean, you will give internet connection for your clients but through your vpn connection?

yes exactly

have you connected the router by vpn first?

  1. what type of vpn server? and read this how to make vpn client, http://wiki.mikrotik.com/wiki/Category:Manual

  2. set the default route for your client.

ok
now i make the VPN and also the routes well but i have a problem witch is alot of sites take a very long time to open and it may request time out i can ping every thing in every where in the clients side, in mikrotik side it replay fast no problem but when browsing we have this lag
i have www.whatismyip.com working it says my vpn ip. every thing seems ok excpt this lag.

after i make some searches i found it may related with MTU or TCP MSS but i don’t know how to fix this problen or how to calculate it. any body could help in this case please?
