Agreed, Source IP is key for SNAT verification!

Source port doesn't really matter here, just saying.

Definitely check the Source IP! That's how you know if SNAT is on.

I thought it was more about the ports, but now I'm questioning if it really is the Source IP after all.

I feel like we practiced something similar, and it was definitely about the Source IP being carried through.

I'm not entirely sure, but I think it might be about the Destination IP instead? That sounds familiar from our practice questions.

I remember we discussed how SNAT changes the source IP, so I think we should look for the Source IP in the tcpdump.

Hmm, I'm a little unsure about this one. I know SNAT has something to do with the source IP, but I can't quite remember the specifics. I think I'll need to review my notes and maybe even look up some examples to make sure I understand how to approach this properly.

Ah, this is a good one. I remember learning about SNAT in class. I'm pretty sure the way to tell is by looking at the source IP. If it changes, then SNAT is enabled. I'll make sure to carefully examine the tcpdump data to confirm.

Okay, let's see here. The key is to look at the packet headers and see if the source IP changes between the external and internal VLAN. If it does, then SNAT is likely enabled. I'll need to double-check the details, but I think option A is the way to go.

Hmm, this looks like a tricky one. I think I'll need to carefully analyze the tcpdump data to see if the source IP is carried through from the external to internal VLAN. That should give me a good indication of whether SNAT is enabled.

Hmm, I'm not sure if I'd trust a tcpdump to tell me about SNAT. Shouldn't I just look at the pool config? *laughs* Guess I need to brush up on my troubleshooting skills.

User 3: I think checking the Destination IP from External to Internal VLAN could also give you a clue about SNAT.

I got this one! SNAT is all about the source IP, so A is the way to go. The other options are just a distraction.

The correct answer is A. By checking if the Source IP is carried through from the External VLAN to the Internal VLAN, you can determine if SNAT is enabled. This is the key indicator of SNAT in action.

I'm not sure, but I think checking the Destination IP might also give us a clue. I would go with D) by checking to see if the Destination IP is carried through.

I agree with Leigha. If the Source IP is carried through, then SNAT is enabled for that pool.
