2 NIC but want to access 3 segment how?

By nle_it ·
Please I need urgent support if you can direct me I?ll be truly pleased. The problem is not that big but it?s complicated.

A HP machine has 2 NIC cards.

NIC 1 is assigned with public IP with default gateway & DNS address.
IP 200.x.x.x
Sub 255.x.x.x
Gate 200.x.x.x
DNS 10..x.x.x

NIC 2 has only IP & subnet mask.
IP 172.x.x.x
Sub 255.x.x.x

NIC 2 IP range is assigned for all internal staff & I can access my laptop & other machines with same IP range 172.x.x.x

Example
My laptop has IP address
IP 172.x.x100
Sub 255.x.x.x
Gate 172.x.x.x
DNS 203.x.x.x

Another Segment
Machine B
IP 192.x.x.x
Sub 255.x.x.x
Gate 192.x.x.x
DNS 203.x.x.x

Now problem comes here that my laptop can access Machine B & can ping as-well (maybe bothe usuing same DNS) but I can't access machine B from my HP machine however i can access all ip with 172.XXX ranges.

Please guide me how can I access machine B from HP machine. I have enabled remote & routing access but I don?t know what to do. Kindly help I?ll be obliged

NIC Solution

by kv2graju In reply to 2 NIC but want to access ...

The solution to your problem is that you have to enable the ICS (Internet connection sharing) for Ist NIC.. and in tcp/ip properties goto advanced tab and select "allow this network connection to share with other users"...
