Cisco ASA Config

thermionic
Not applicable
Hi,

I've been trying (and failing) to setup a Sure Signal to work over our Cisco ASA 5510 firewall, and having "fun"

At the moment, I'm still trying to get the @ light to go solid...

After following http://forum.vodafon...ght-2-flashing/ and http://forum.vodafon...7-setup-issues/

I used CSM to setup the ASA, the relevant parts of the config are as below


interface Ethernet0/1
nameif inside
security-level 100
ip address 255.255.0.0
!
interface Ethernet0/2
nameif Venus
security-level 0
ip address 255.255.255.128


object-group network Vodafone_Sure_Signal
description Vodafone Sure Signal Addresses
network-object 212.183.133.177 255.255.255.255
network-object 212.183.133.178 255.255.255.255
network-object 212.183.133.179 255.255.255.255
network-object 212.183.131.128 255.255.255.192

object-group service VodafoneSureSignal
description VodafoneSureSignalPorts
service-object udp eq ntp
service-object udp eq isakmp
service-object esp
service-object tcp-udp eq 4500

access-list CSM_FW_ACL_Venus extended permit object-group VodafoneSureSignal object-group Vodafone_Sure_Signal host

mtu inside 1500
mtu Venus 1500

global (Venus) 231

nat (inside) 231 255.255.255.255

static (inside,Venus) netmask 255.255.255.255

access-group CSM_FW_ACL_Venus in interface Venus



The , , and are just to remove site specific information

DHCP is used from an internal DHCP server, which sets the internal address (reserved), two accessible internal caching DNS servers, and the default gateway of the ASA firewall, as well as NTP servers etc.

The ISP connection is a 100mb conection in the UK.

If I do a packet capture on the ASA, I see traffic on udp/4500 in both directions, but the light just keeps doing its slow flash.

If anyone has successfully managed to get a Sure Signal to work with a Cisco ASA (ideally in a CSM managed environment), I'd be very interested in hearing from you.

Cheers

Are you able to gather a wireshark trace at all?

Im currently watching a Suresignal trying to activate (since I factory reset it earlier as part of troubleshooting) and it is reporting that a hostname is unable to be resolved which is stopping provisioning.

Hi thermionic,

Firstly, a very warm welcome to the eForum Family, it's always great to see new faces on here :).

Unfortunately, we're not Cisco certified so wouldn't be able to help with specific firewall setup, maybe one of our helpful eForum members has set this up before and has working instructions? Does the Sure Signal work with the firewall not in place?

If you didn't understand my original post, it would have been better to ask for clarification than suggest what you did.

Hi Gavin,

I hadn't bothered setting up a span port and monitoring that, I've just been doing packet capture on the ASA to check that traffic was flowing, and I was only seeing traffic to the .177 address on udp/4500.

Have you configured the DHCP reservation to point at an internal or external DNS server ?



I was feeling a little masochistic this morning, so called in to the 0870 number, and thence to an 0845 number and after approx 8 IVR prompts asking me for my mobile number, then PIN, then option 3 and option 4, I gave up and called in on the main number, explained that I'd been going through IVR hell and asked if they could put me through to somebody instead of putting me back into the IVR queue. I eventually managed to speak to somebody 45 minutes later...

They initially told me that they were Tier 3 support, and that they only support UPNP routers...

After yet more time, and three reboots later, including on where the lights were cycling between 1&2&3, 1&3, 2 which apparently was a light sequence that he hadn't heard of before, he checked with somebody else, and said that it needed to be replaced.

We hadn't even touched on the port and protocol forwards...



My initial thoughts on this are that Vodafone rushed this to market

1/ The complete lack of any local diagnostics is ridiculous,

2/ The use of IPSec and multiple port and protocol forwards that it requires. If they had used a HTTPS VPN such as OpenVPN then they could have done all of it over a single port.

Hi,

I have had the SS using both an internal DNS server and a set of external DNS servers. The SS gets very upset if one of its hostnames fails to respond, it then tries to talk to an ip in the 172.X.X.X range.

The light sequence you have seen, I can also reproduce and I put that down to a factory reset/firmware reload in progress (from watching the limited activity via wireshark).

I have a variety of CPE that I can put this unit behind yet no difference has been seen to the behaviour of the unit since this mornings factory reset.

Hi Gavin,

Did you see any traffic on udp/4500 going to any of the addresses, or just failed DNS lookups ?

I do wonder why they need a DNS lookup when they set IP ranges for the port forwards...

Hi thermionic

I have the same issue ASA with 100mb leased line and have configured the same rules.

Did you ever get the VSS to connect?

 

Thanks

I'm replying to this thread late but have just found it.

 

I have just set up a new Sure Signal behind a Cisco ASA 5505 on a Zen Internet 'Fibre Active' service. The ASA is running v9.0(1) and sits behind a Cisco 1921 which connects to a BT Openreach modem (VDSL2, PPPoE, MTU1500).

 

The VSS works fine in this setting with no need to forward any ports. I simply added the line  'inspect ipsec-pass-thru' to
