al-siput 2 Report post Posted February 27, 2008 (edited) Boleh ke wujudkan 25000 host bagi address space nih?192.168.0.128/25cemana nak buat? Edited March 2, 2008 by al-siput Quote Share this post Link to post Share on other sites
prontoxp 2 Report post Posted February 27, 2008 (edited) Kalau ikutkan kiraan tu just ada 126 Ip live ... masalahnya bagi aku keterangan tu mcm x lengkapKalau LAN tu tiap2 area tu 192.168.0.128/25 nak cukupkan 5000 kurang2 ada 39@40 LAN router yg mampu di map ip nya dari Main Router yg subnet besar contohnya 10.0.0.0/8 atau 172.16.0.0/16 tapi LAN Ip user/site just guna 192.168.XX.XX /24 - 30jadi dlm tu tadi ada 4 router... kira boleh la pecah lagi buat NAT dgn IP mapping ...1 Router amik la 10 SUb LAN lagi...Itu ikut pemahaman aku la.. sbbnya aku penah buat ip map ni kat TNB ... penat aku nak buat firewall rules tu...apa pun aku tggu gak la kut soalan ni tak logic atau ada kaedah lain yg aku masih tak tau...

TRUNASUCI 15 Report post Posted February 27, 2008 25000 hosts guna prefix/25? Impossible bro, mana ko dapat soalan ni... err aku tak pandai sgt bab2 network ni, tapi kalu untuk class C, commonnya takpenah jumpa la /25.. kalu /24 tuh biasa la.. kalu nak lebih dari itu, pakai class B atau A..sorry aku jahil bab2 ni tau sket2 je. tp itulah yg aku belajo pun..haah soalan aku pun sama.. mana dpt soalan ni? p/s: kalu dia tulis /8 ke /16 ke rasa mcm logikle sikit...

prontoxp 2 Report post Posted February 28, 2008 Aku rasa kalo diagram tu guna IP VPN/Direct may be la dia buat ada 5000 host setiap satu SUB link guna NAT / Firewall .. Lagipun B3 space tu tidak dinyatakan dgn jelas ape dia device nya dan apa guna 192.168.0.1/25 sbbnya aku kat N9 ni ada buat link semacam tu ... Kalau switch dgn IP layer tu saja mmg imposibble...contoh IP Direct tu 192.168.0.120 / 25 (ini link dari TM ke remote End Point sahaja ) lepas tu dlm NAT/firewall ni ada plak 4 Port , each port boleh buat lain2 segmen dan IP design... bayangkan port 1 gunakan IP design (192.168.0.1) 172.16.1.0 - 172.16.20.255 , Port 2 IP (192.168.0.2) 172.16.21.0 - 172.16.40.255 dan seterus nya la sampai abis port 4 Quote Share this post Link to post Share on other sites
