Access For Sip Client

[quazimotto]

Greetings! Its me again. I need to allow a Sip client to access the network and end up at the Voice Server. I would like to use the main ip address and point anyhing Sip to the Voice Server. I have a PIX 501 6.3(5).

Any ideas are appreciated greatly.

Thanks/Quaz

 

[unclerico]

add

fixup protocol sip 5060
fixup protocol sip udp 5060

access-list outside_access_in extended permit tcp any interface eq 5060

nat (inside,outside) tcp interface 5060 <voice_server_ip> 5060

access-group outside_access_in in interface outside

I hate all Uppercase... I don't want my groups to seem angry at me all the time! =)

unclerico,

Thanks for the response. The pix will have non of the code from your post. The pix doesn't like " extended " before permit. And it says "invalid number of interfaces specified" when I enter the nat command. What do you think ? I am sending conf for you to look at.

I appreciate your help greatly.

Quaz

sorry, I screwed up the commands:
1) omit the extended command from the ACE. i'm used to newer code that adds it in
2) it is supposed to be static not nat. so it should be static (inside,outside) tcp interface 5060 <voice_server_ip> 5060

I hate all Uppercase... I don't want my groups to seem angry at me all the time! =)

[quazimotto]

unclerico, WHen I delete the extended from the command the PIX is telling the interface <eq> does not exist.

Quaz

 

[unclerico]

i forgot that your access-list on the inside is labeled outside_access_in so issue no access-group outside_access_in in interface outside. Add in access-list outside_in permit tcp any <outside_ip_address> eq 5060 and then apply it access-group outside_in in interface outside

[quazimotto]

unclerico,

Here's what I got the PIX to take. WIthout " host " in the command it would not take cli. Said " Invalid Interface eq ". Here's what it took.

access-list outside_access_in permit tcp any host 76.116.43.xx eq 5060
access-list outside_access_in permit udp any host 76.116.43.xx eq 5060

static (inside,outside) tcp interface 5060 192.168.1.25 5060 netmask 255.255.255.255 0 0
static (inside,outside) udp interface 5060 192.168.1.25 5060 netmask 255.255.255.255 0 0

Its no good. Sip client can not see server inside. What must I change?

Quaz

 

[unclerico]

Turn logging on, try to access the voice server, and then look at the logs

I hate all Uppercase... I don't want my groups to seem angry at me all the time! =)

[quazimotto]

Put "access-group outside_access_in in interface outside" command in and now the Voice Server sees the SIP client. It is not registering. I will start logging. Thanks for your patience.

QUaz

 

[quazimotto]

unclerico,

The server sees the SIP client but does not register. I ran a debug. Please have a look and tell me where the problem lies.

I looked at it and it looks as if everthing is going good till it gets to" Unable find xlate table for 10.10.10.142 " at the end.

Thanks/Quaz

[unclerico]

let's back these two commands out then:
no fixup protocol sip 5060
no fixup protocol sip udp 5060

try registering again and let us know how she goes

When I removed the two lines from config and turned on debug sip, nothing happened. No sip activity got in.

[unclerico]

what sip solution are you using??

Session Chat and AdorePhone. Two Iphone apps. When I am on local lan they register in a heartbeat. I am trying a different router at remote end. I will send my WAN address from the remote. The debug log seems to imply that the Host router loses site of Wan IP address of the remote.
" Unable to Xlate Local Blah Blah ". I am curious to see if that works.

Thanks/Dave
