Hi,

 

Unfortunately there is no external document for the same but there is an internal PR which says that SIP for custom LSYS is not supported and it is supported only for root LSYS.

 

I have found a below discussion thread from Forum as the only public document which tells the same thing-

https://forums.juniper.net/t5/SRX-Services-Gateway/LSYS-on-SRX-are-there-any-feature-restrictions/td...

 

Hope this Helps. Smiley Happy

Hi, Basically, in the internal PR, engineering has confirmed that SIP alg is not supported in an Lsys other than the root Lsys. There is not much to share anyway. We can look forward to creating a KB document stating the same if needed. HTH ! Regards, Sahil Sharma

Re: Does SIP ALG support on LSYS SRX5800?

Hi ,

 

So in that PR mention if we use LSYS in the SRX and at same time need SIP ALG (NAT) to be use in that LSYS then it should not work? In other word we need to use root system if need to use SIP ALG (NAT) traffic? Why juniper not state this in the public doc because i'm just do migration using LSYS but suddenly SIP ALG not work. They should put the weakness of LSYS in the first place not hidden this important info.

 

 

 

Thanks
