Hi I am using Mikrotik 2.9 and doing masqrade to my lan ips and whats the problem is my static ip is always being blocked in spam and i am getting mails that my mikrotik is an open proxy. please help me in this regard
Add a firewall rule that allows access to proxy only from internal lan:
/ip firewall filter add chain=input src-address=!192.168.168.0/24 \
protocol=tcp src-port=1024-65535 dst-port=3128 action=drop \
