finally set up PCC and I have a feeling that traffic for https might be coming in on a different port than it is going out so I’m trying to figure out if there’s a way to determine this using Winbox. using the Packet Sniffer I see a whole bunch of items, but no way to filter only on a specific src or destination address. any suggestions? I know the LAN IP and the destination IP addresses as well as it being https connections. what can I do?
The torch tool lets you do this in real time. Have you tried that?
yep, I’ve taken a look at Torch, however that looks more useful in determining where all the bandwidth is going unless I’m mistaken. I’m looking for something that can tell me which of the two WAN connections I have set up with PCC traffic is going to, specifically so I can determine if outgoing traffic is returning on the same WAN connection that it left on.
Unless you’re running some kind of dynamic protocol that lets you use the same IP range on both WAN connections, there’s no way that it can return via anything other than the one you send it out because each WAN is going to have its own IP address to masquerade with, and furthermore, most ISPs correctly filter the source IP of packets you send to them… so unless ISP1 doesn’t have anti-spoofing in place and you’re using SRC-NAT rules (instead of MASQUERADE rules) which are misconfigured to send packets to ISP1 using the address of ISP2… unless that’s all true, you’re getting replies over whatever interface you’re egressing traffic through.
