ICMP is not currently supported by TProxy directly. However you can use raw sockets to achieve the same result. On Wed, 2004-11-24 at 23:53, Javier Govea wrote:
Hi,
I am writing an proxy for different appliacations. So, far it's working with UDP and TCP. All packets arriving at my proxy machine are redirected, with iptables, to the the proxy server, which extracts the final destination of each packet. For the UDP case I am using a tproxy rule to forward all traffic to the proxy server. The proxy server is using something similar to redirect-udp-recv.c to exctract final destinations.
Now, I need my proxy to support pings and thus ICMP packets. Can use the tproxy to forward ICMP packets to my proxy??? and to extract final destination similar to redirect-udp-recv.c??? If this is not possible, is there any alternative?
Thanks in advance Xavier
