IP Forwarding for Internet Access from one machine to another

I have already done in my server with nic bonding for the purpose increasing the speed of internet but whether it is possible to have the bridging the servers after using the NIC bonding
No... that doesn't really make sense does it? Bonding your NICs makes them "one" interface so you wouldn't be able to bridge between the two.

He is correct, bonding / teaming makes bridging impossible.

i dont want to bridge now.
i need to forward the ip for the server -

i need to forward the ip for the serverThat would be port forwarding on the router / firewall.

there is no router present,i need to make my ubuntu server as a router here

So you do need bridging?

My scenario here is the master server has three nic ports(A,B,C) with two nic ports(A,B) are bonded and now the nic port(C) is not bonded.
The internet is coming from the nic port C and the nic port A,B are connected with 192 series IP which is communicating with the slave servers .
The slave servers have two NIC ports(A,B)which are also bonded and it has the IP in 192 series.
Now the internet from the NIC ports C of the master server has to be provided to the slave servers and the slave server should have the internet.

You will still need a bridge between port AB and C. Here is some info from Ubuntu. https://help.ubuntu.com/community/Router

I have already used the iptables to configured by this command after
nano /etc/sysctl.conf
Enabled the IP forwarding and tried
sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADEIn my test machine worked properly but at the server it does not working properly.

Bridging and routing are different things. One is layer 2 and one is layer 3. But neither will work if he bonds the NICs.
