ASDM connects from one interface only.

John Bachman
Level 1
Level 1

 

Hello,

 

I can only connect to ASDM from hosts on192.168.1.0/24 (inside interfaces on VLAN2)

Other hosts on other VLANs cant connect... Is there a limitation of the ASA to only have one VLAN allowed to access ASDM ?

 

I can`t https://192.168.1.1/admin/public/index.html from 172.100.20.100. but it`s ok from 192.168.1.0/24

 

I can ping 192.168.1.0/24 from 172.100.20.0/24, so it`s not a connectivity or NAT issue

 

http server enable
http 192.168.1.0 255.255.255.0 inside (VLAN2)
http 172.100.20.0 255.255.255.0 test1(VLAN12)

 

Any help greatly appreciated.

Hi,

"I can`t https://192.168.1.1/admin/public/index.html from 172.100.20.100. but it`s ok from 192.168.1.0/24"

Have you tried to access asdm with https://172.100.20.1/ ?
As your traffic should come from there right?

 

If you are going to access 192.168.1.1 then you need to configure:

http 172.100.20.0 255.255.255.0 inside

Hi,

No, there is no limit to only access asdm from one vlan.
I think we need some more information, can you provide interface config and route config?

br, Micke

Thank you, as I said I can ping between VLAN 2 and VLAN12, so it is not a connectivity issue, it is more a security or access issue from VLAN 12 hosts.

br, Micke

That worked. I cant believe the ASDM is attached to the local interface...

Thanks so much !
