Bigip APM setup in AWS is not working

Hi All,

i have configured APM instance in AWS with multi-nic setup. now installed APM for network access. i am able to login via AD on webtop and also able to launch network access but not able to access internal resources. i have used snat pool in network access but from outside with vpn client machine when i try to ping any internal machine, it shows destination host not reachable and ip comes as bigip selfip.

are you internal systems allowing the access from the BIG-IP? if you haven't changed it then there are pretty strict internal ACLs on AWS systems, with those active you can't suddenly access them from the BIG-IP.

so allow access from the BIG-IP IPs for ICMP and other protocols you need.

Yes. i allowed on AWS group security - Bigip selfip and SNAT pool list ip (which is internal segment ip which i configured on VS and network access too that when network access initiates from outside, after getting an ip from lease pool, that snat ip will communicate instead of automap). but when ii connect from network access and start making ping of any of the internal resources, i got destination host not reachable or RTO from selfip . i also tried to create an ACL in network access and open any from outside for internal server range.

what if you ping from F5 itself to internal server?

do you have split tunnel or full?

what does packet capture (tcpdump) show?

from F5 itself i am able to ping internal server because i have configured my internal AD server for APM authentication and i am successfully able to login in webtop with AD and also AD query is happening. its split tummel. i also tried to change in full n=tunnel but no luck.

do i need to configured ACL in network access?that also have created from source any to destination AD server.

when you don't configure an ACL then you should just have full access. it is not required for it to work or such.

kinda tricky now, it might be the config of the SSL VPN or something else.

have tried a packet capture on the big-ip? just to see if the traffic is seen there and is seen leaving the big-ip towards the internal server?
