Re: NAT how to make it work

Did you dou create your nat pool ?

How many IP address do you have one or multiple ?

It seems like you are missing the nat pool config...

Re: NAT how to make it work

nat pool? y its required ?

wht i want is any traffic hitting vlan 102 interface for destination as proxy B shd get translated as proxy A..why a pool is required? so with my current config when i ping the reply comes from proxy a and nt b..so translations is working i guess..but when i try to connect on port 80 or any IP traffic it isnt working

correction..i mean any traffic for destination A coming on vlan 100 shd get transalted to proxy B and i cd ICMP reply from proxy B when i ping A but no IP traffic works...so the routing of traffic is happening when traffic comes on interface 100 ..how do i make it work for IP traffic

Re: NAT how to make it work

Hi,

Why do u telnet on port 80

telnet default port is 23

Try using that port it should work.
