Interface IP of Mikrotik

Fri May 05, 2023 5:29 pm

Hello all,
I have a below scenario (try to upload an image)


Image


ISP gives a VOIP line but their information is almost incomprehensible for me .
I have the following information from ISP's side :
>> Range of IP voice
>>PBX IP (suppose : A.B.C.D)
>>Gateway IP ( suppose : E.F.G.H)

GRE :
>> GRE Tunnel range IP
>> Interface GRE Tunnel
>> IP GW Router
>> Remote add GRE Tunnel (public IP)


IP PBX setting on Issabel
>>Host
>>Type
>>qualify

and
Several lines (As a static route) should be added on both Mikrotik and Issabel
IP route add ......................via Gateway

So my queries are :
1---Should I assign PBX IP(A.B.C.D) to the Eth1 of Mikrotik (WAN's IP of Mikrotik) ?
2---Those lines of static route :
static route on Mikrotik should pass through E.F.G.H(Gateway IP) ? Am I right ?
static route on Issabel should pass thorugh IP LAN of Mikrotik(Eth2) ? Right ?
3--- On Issabel how I should add static route ? should I connect with putty and write it there ?or can be done by GUI ?
4---While sbc's IP is different from what I have configured in LAN area , I have to run NAT (both srcnat and dstnat) on the Mikrotik ? Correct?
5---Modem should be bridged to the Mikrotik , but what I could do if bridge option not exist on the modem ?
6---Why ISP gives GRE Tunnel range IP ?
7---Why ISP gives range of IP Voice ?



Thanks and Regards
