SUCCESS!!! XD after several days of stupidity.. salamat kay kuya gigz!!! ) alam ko na kung ano problema ko.. wahahaha pasenxa na din sa pangungulit.. di naman pala siya ganun kahirap... isa akong malaking BOBO wahaha.. SOBRANG dali lang pala nito.... kung ano2 pa pinagaaral kong technical materials.. matagal pala magloopback yung message kapag IMBA SLOW yung connection na gamit ko -.-"basta salamat sa mga examples dito tsaka kay tita gigz )) igiling mo!!
bale ang ginawa ko lang sir glutnix eh nagportforward papunta sa ip address ng ethernet shield... sabi nga ni tita gigz kapag nakaportforward yung router papunta dun sa ethernet shield lahat ng packets na pumapasok sa public ip address eh napupunta dun sa private ip address.. see here http://portforward.com/iba-iba yung way ng pagpoportforward for different model ng routers...eto yung procedures na ginawa ko..1.kinonfigure ko muna yung ip address ng ethernet module.. through lan.. (nasa manual kung pano.. tsaka nasa tutorial ni sir seven)2.portforward.. papunta dun sa ip ng ethernet module.. ang port na ginamit ko is port 23 for telnet...3.make sure na yung mga ip address ng ethernet module tsaka sa computer eh hindi magcacause ng error. (tama ba toh?? wahaha )4.after i-configure yung mga ip addresses.. ang hardware setup ko eh ganito:HOST:ISP----->router----->ethernet shield (with rx tx connected)CLIENT:Globetatoo----->Computer----->vb program5.yung program ko sa vb.. ang ginagawa lang niya ay:a.Connect sa host's IP... tapos yung port (public ip address/external ip address ng router)yung nakikitang ip address and port dito yung kinocall ko... http://www.ipchicken.com/b.send and receive message... tapos ididisplay lang sa textbox..6.ayan.. ganyan po.. sana wala ako nakalimutan XD
Some home routers refer to a DMZ host. A home router DMZ host is a host on the internal network that has all ports exposed, except those ports otherwise forwarded. By definition this is not a true DMZ (Demilitarized Zone), since it alone does not separate the host from the internal network. That is, the DMZ host is able to connect to hosts on the internal network, whereas hosts within a real DMZ are prevented from connecting with the internal network by a firewall that separates them, unless the firewall permits the connection. A firewall may allow this if a host on the internal network first requests a connection to the host within the DMZ. The DMZ host provides none of the security advantages that a subnet provides and is often used as an easy method of forwarding all ports to another firewall / NAT device.
