 Re: Does this tcpdump result has any error?
Rather than running tcpdump | grep <IP>, it's much more efficient to use the tcpdump filters - e.g. tcpdump -i eth2 host 192.168.32.133
But that session looks OK to me. Read up on how TCP works. Notice that you've got communications going in both directions there, with SYN, ACK, PUSH and RST packets - that shows that there is a valid path right through.
Typical firewall problem might show up as only SYNs coming from one side, with no reply. Or occasionally if there's a reply routing problem, you might have a SYN from one side, a SYN/ACK in return, but then no follow up ACK. |
