VPN

Hi Guy’s
i have a Mikrotik router and
I have some Client that connect to my network with PPTP VPN to reach some local server’s . the problem is
i don’t want their internet traffic ( access to web and Email) goes to VPN tunnel . how can i ban internet traffic not goes to tunnel?
how can i inject some route to their PC routing table when connect to my VPN server ?

I need help…some idea ..

The client should be setting their VPN to NOT SEND ALL TRAFFIC, if you don’t want them sending their traffic over your ISP.

If you put a firewall rules in their to deny their traffic access to the WAN… That would get them to disconnect or at least look up split tunneling VPN.
