Re: [Users] SER as loadbalancer and NAT

Andreas Granig wrote: Just an idea regarding load balancing and NAT using the Path header: When having a scenario like this: [uac] -> [nat] -> [sip loadbalancer] -> [sip proxy] Then I could construct a Path header like the following at the load balancer for REGISTERs: Path: <sip:<own-address;lr>, <sip:<received-address>;lr>;nat=yes Which is saved at the sip proxy when acting as registrar and will be converted into a Route header for subsequent requests towards the uac. This would allow loose-routing on the load balancer to traverse the client's nat: In addition to removing the first uri (the own) from the Route header, loose_route() would check for the "nat=yes" flag in the next uri and would remove that uri from the Route header too after setting it as dst-uri. Would this make sense, or are there more-elegant/simpler/better ways for achieving such a loadbalancing scenario (keeping in mind that there might be more than one load balancer and that it has to work with NAT)?
