Let your network IP address is a.b.c.x with 0<=x<=255 and a,b,c as
constants.
normally a.b.c.1 will be the gateway IP. If you want to put Gateway in SJ office, the machine with this IP should be there and and all other machines should specify this IP as in their gateway IP setting. Now all machines in the network(having IP a.b.c.x, and it doesn't matter whether machine is in HB or SJ as long as it is phyically connected using ur leased lines) will access outside the network through this gateway machine only. The DNS server can be SJ or HB , but keep it in SJ as you are planning for putting most of the servers there only ( will centralize management). Regarding mailserver you can have two mail servers i.e. foo.com in SJ and in.foo.com in HB. Even one mailserver at SJ may be sufficient as there will be no problem in accessing your mails that way also. you just have to pay for registration of foo.bar( or whatever) and then u can have <anything>.foo.bar by making DNS entry. hope it meant something ;-) surinder Sreenivas wrote: Hi List, We have an office at SanJose and at Hyderabad India, which are connected thruogh a leased line.Hyderabad LAN, SJ lan will be in private range of ipaddresses and we will have our Internet services at SJ office i.ewe will have our internet gateway DNS,Mail server,firewalls,webservers,VPN gateway etc at our SJ office, To achieve this what would be the best design, and also is it possible to have mail server with private ip address at our hyderabad office which recieves mails from out side our domain.i.e we will have our domain server at SJ office with name foo.com with public ipaddress and india.foo.com at our Hyderabad office which has private ip address ( 10.x.x.x) if it is possible how to do this. and if not what would be the other alternative. Can we have firewall in between our LANs if so what is the best way we could achieve this. What are the other issues that i have to consider in building this network. I have been working as sys admin and dont have much experience in networking can any one please me.Thanks for any help in advance. CheersSreenivas M |
