ASA 5520 Flow is Denied by Configured Rule "INSIDE to OUSDIE"

[dvargas@nwfcu.org]

I purchased a 5520 with an SSM20. Since day one the configuration "Default" has been blocking traffic from INSIDE to OUTSIDE>. After doing some reasearch i thought that i was getting blocked by the SSM20 but that has been cleared and HW-module module 1 shutdown. So technically  nothing should be block the traffic. 

For now i have a verizon router with a static route to point the INSIDE Network off of the outside IP address within the ASA. However, I can see that traffic is flowing and being reset but cant figure out what is blocking the traffic.

Can sombody give me a hand... I've been on this for a month now and yet learned a lot with this troublesome ASA.

What is the source and destination of traffic you are testing with?

Have you tried running packet-tracer? e.g.:

packet-tracer input OUTSIDE tcp 8.8.8.8 1025 192.168.200.2 80

(addresses and source/destination ports shown are examples - adjust to suit).

Also your ACL "access-list INSIDE_access_in"and associated access-group command aren't necessary.

[dvargas@nwfcu.org]

Yes, and it appears that the flow is accepted. I'm wondering if the static route i have in the Verizon router is not being granted.

Verizon static route: 192.168.200.0 255.255.255.0 192.168.101.101

From ASA:
Packet-tracer provided does go through all Phases and being allowed.
What i dont understand is that why may i being able to ping from the host to the gateway but not the internet. Again i'm wondering if the verizon router is not playing nice w/ routing the traffic back but if ping works then it does.

the ssm 20 is powered down and dont have any service policy rules in place either...

Without wishing to state the obvious the router is setup to NAT the source IPs isn't it ?

Jon

[Marvin Rhoads]

Ha - Jon you posted that while I was writing the same thing!

[Jon Marshall]

Hi Marvin 

No problem, glad we said same thing :) 

Jon

[Marvin Rhoads · Accepted solution]

It could be that the Verizon router is not configured to do any NAT for your inside subnets.

That would explain that it replies to ping from the inside subnet natively - the ASA and the static route all working as intended.

If traffic from the inside subnet to the Internet is coming from a network that the Verizon router isn't NATting, it will hit the public Internet with its native RFC 1918 address and not be forwarded.

[dvargas@nwfcu.org]

Marvin & John.

Thank you for your solution but well... not with this particular Verizon router but i have done this setup in the past and has worked as it is. I'm not an expert with NAT but wouldnt/shouldn't that traffic be NAT'ed as well?

Are you suggesting that I should run NAT from the ASA on my OUTISDE interface?

[dvargas@nwfcu.org]

Yes, it appears that my old Verizon router is not properly NATing my traffic from the INSIDE network. After doing dynamic "PAT" NATing on the ASA i was successfully able to reach the internet.

Which is a good reason why i got the ASA... to learn it is def' a different beast than the SRX
