I have problem - my IIS Provider closed 25 port smtp-out for security policy.
i need to config Mikrotik RB 450g - need smtp-out through web-proxy
wan ip:1.1.1.1
web-proxy ip:2.2.2.2:3128
lan:172.16.0.1
Please help me, to write a script to resolve my problem.
You want email to use a web proxy? Doesn’t work.
What exactly are you trying to achieve? Who is your email provider? Most providers allow you to use the SMTP Alternate Submission port of 587. You can take packets originally destined to your ISP’s email servers on port 25, and rewrite them to port 587.
/ip firewall nat
add chain=dstnat action=dst-nat protocol=tcp dst-address=<some.ip.addre.ss.> dst-port=25 to-ports=587
