    kinsa na nakasuway og gi attack inyo Mail Server?

    As in namugnaw jud ko ato nga time kay kami tanan among Web browser kay naay message mogawas something like "error i can breake rules to. goodbye" i forgot exact words. Text ra and white background. Dili na mi ka browse sa net.

    what i did, i restored settings and rebooted the router (pfsense) 3 times, then a few moment after the router rebooted, mobalik2x jud sya.

    Ako gi check ang states = naa jud mga unusual connections sa mail server . mga suspicios ports.

    What i did, i turned off the mail services sa mail server then nabalik ra amo web connection then ni pas2x dayon balik.

    Now = ako na gi separate na ang Mail Server (DMZ) then ang ports few rules nalang sad (before kay NAT port range man gud). Im not a network admin, netwoking newbie lang nga nagmanage sa small netwok sa office. nagkat on na jud ko.

    unsa kaha tan-aw ninyo ato? unsa man tawag ato nga attack?

    Bai Gab, unsang klasehas Mail Server duna di ay ka? Updated ba iyang patches? Morag gi-attack og morag dili ang sitwasyon nimo. Probably inyong network ni-kaylap ang kagaw nga Trojan Virus or Malware pero dili ko sure.

    Unsa di-ay currently imong setup? I mean like (Router/Firewall > Switch > Server > Workstation)? Ways to protect sa imong mail server kai ibutang nimo sa private network unya kanang sa DMZ butangi lang og Mail Relay server.

    Any mails coming from outside anha ra kutob sa DMZ unya ang mail relay server maoy mo contact sa Mail server nimo sa private but you need to protect sad ang server sa DMZ. You need to make firewall rules outbound nga mo block all traffic sa SMTP (Port 25) except sa imong mail server ra.

    Kana lang osa akong ikatampo nimo.

    if you are leased 1mbps sa imong ISP, there's no way you can double it up logically or what.. the only way is modifying allocated bandwidth for you via account (ISP network operations center)...
