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...

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

Hi,

Why do u telnet on port 80

telnet default port is 23

Try using that port it should work.

i guess u rnt understanding? http port 80 is wht proxy listen to..so if do a telnet porxyip 80 i shd see a connection.. a black screen..i cant connect on any IP port on the destination IP address with my config..but i can ping and it get translated to the destination IP..hope i m clear now
