Reach published services from internal network

bridge_it — Mon, 11 Mar 2019 23:03:29 GMT

Hi.

I have a ASA 5510 with one external interface (eth0) and one internal interface (eth1) with 4 VLAN interfaces 'attached' to eth1.

I have external services published on VLAN 2, but are unable to reach these services (i.e webmail.domain.com) from the physical eth1 (or any of the other VLANs)

I am able to reach these services from external sites, but as long as I am on the inside network I am not.

When reading the log I see the following:

Service #1 - webmail.domain.com

Main IP for outside network is 109.x.x.12

IP for service webmail.domain.com is 109.x.x.15

Built outbound TCP connection 1005229 for OutsideISP:109.x.x.15/443 (109.x.x.15/443) to insidenetwork.local:192.168.x.57/2758 (109.x.x.12/33854)

And that is it, after a while the connection times out and I get a Teardown message in the log.

Hi Thomas,

Coould you post your configuration as well, it would be better to understand the issue.

Thanks,
