They will still be able to use it. Naka declare rin naman sa firewall mo yung DNS na iyan.
New set-up ba yan or new issue?

Nirekta na pala si IP phone sa modem. Hindi na dumaan ng FW. Hehehehe, Iwas gawain under FW.
So ngayon ano na ang bagong set-up? Lets just say na hayaan mo na yang ganyan set-up to give you less headache pero dapat lahat under FW and si FW ang bahalang mag manage lahat ng routes.
Ano ang gamit ni PLDT Enterprise? Para lang kay IP Phone? How many IP Phones do you have? How many PUBLIC IP addresses binigay sainyo ni PLDT?
If more than 1, gamitin mo yung isang IP for FW, direct na kay PLDT Modem si FW.
Need mo iconfigure ng tama si firewall para makakuha ng IP addresses ang workstation mo. There is something wrong with your DHCP server, or merong conflict sa IP addresses nyo. You need to plan.
How many workstation?
How many servers?
Sa practice namin static lahat ng workstations and servers, that includes IP phone. At yung makikigamit lang ng wifi or makikikabit ng laptop using cables, that is part of dynamic IP ranges.

wala pa namang bagong setup sir.
sabi kasi ng koreano namin ung gamit ni PLDT Enterprise is para dun pumasok ang Public IP na galing sa Fiber Home Modem (ginawang Bridge kasi ung PLDT Enterprise) para sa IP Phone nila. 5 IP Address sir. 5 sa IP Phone 1 sa Firewall. bale ung isang IP phone is ginamit ko ung network IP namin pero gumana ung IP Phone nya bale ang nagagamit nyang IP is ung kay firewall. tinesting ko na ung dinirect ko kay FW ung Fiber Home (Main Internet Connection) at kinabit ko sa Unmanageable switch ung mga IP Phone pero hindi nagana ung IP Phone kaya pinabalik sa ganyan ung setup ng mga cable at ung dalawang PLDT Modem.
nasa plano ko na rin nmn ung pagayos ng FW namin pero hindi ako makasingit kasi andming nagcocomplain na walang internet connection at walang file server. IP Conflict? halos lht nmn ng Laptop/Desktop is nakaObtain nmn.
60 ung workstation ko sir
as of now wala pang Server samin magiimplement pa lng ng system samin.
sa kabilang building kasi is iba ung IP Address bale dito sa main building is 100.1 pero sa 2nd building is 0.1 pero naAaccess ko nmn ung modem ng AP. dun lang ako nagtaka sa AP nila na 0.1 pero nkakaAccess ng Firewall pero ang gateway nila is 100.254 and wala nmng nkaIndicate na 0.1 sa FW namin. msyadong magulo tlga ang setup dito sa company. hindi ko alm kng pno sila nakakapagWork ng ayos pag ganitong setup ng network nila. balak ko sanang magpakuha ng team na tutulong sakin na ayusin ang network ng company kasi hindi ko kaya ng ako lng magisa na isesetup ang network nila kung gagawin kong static lht.

^Yep kase naka bridge mode si modem. Depends also kung STATIC PUBLIC IP binigay sayo or PPPOE type ng connection, either way it should be easy to configure. I can see the problem is yung NAT behind FW, walang route palabas ng FW. Medyo mahirap mag configure ng FW lalo na kung enterprise level. Kase magkakaiba yan ng configurations, others automatic NAT others need mo talaga ispecify yung routing nila.
I suggest mag try ka sa isang system lang.
since naka bridge mode is modem, try mo gayahin settings ni PLDT enterprise kay FW.
Make sure to backup everything, yung config ng PLDT Enterprise at FW, before ka mag modify ng config.
I establish mo muna sa isang system behind FW. Doon ka mag config, now I can see na NAT ang problema mo at nahaharangan ni FW ang IP Phones mo. Make sure na naka pass-through lang mga IP Phone mo.
Back-up config. Better gawin mo yan during rest day. Just ask for additional pay for it else kawang gawa na lang para maresolve mo na lang ang problema.
Ganito ang better topology
Modem -> FW -> Network Switches -> Workstations/IP Phones/Etc
Sa ganyan setup, mas protected ang network mo since ang main control sa FW.
You just need to config proper NAT in your FW.
Gamitin mo muna yung isang PUBLIC IP ni IP Phone para kay FW.
Again, backup everything.

^ Kung napapasok mo yung PLDT Enterprise Router. Makikita mo yung details ng PPPOE, thou baka hindi visible ang password.
Pasukan mo na lang ng walang bayad, kase sasakit parin ulo mo kung tuwing weekdays eh magrereklamo sila sayo. Im not familiar kase sa FW nyo, so I cannot give specific guide.

Fortinet din gamit namin Paps almost 70 Computer din. tas ganyan din nagiging problem. Tas ang pinaka solution na gingawa ko dyan after ma set up yung mga policy is yung ma mga connection ng equipment Tulad nung pinakita mo kasi yung Firewall mo at yung PLDT nag bibigay ng IP kaya nag kakagulo yan kaya nag kakapali palit .
