Hi All

I have a problem on my ClearOS setup. I have 2 internet connections using Wan1 and Wan2 with 1 Lan connection. Both Wan connections are set as primary in wan balancer with the first Wan1 connection getting priority using weights. Voip works fine until Wan1 goes down. Wan1 shows as offline and all traffic goes to Wan 2 except my VOIP phones don't automatically reconnect to the hosted PABX. It will reconnect on Wan 2 if i reboot ClearOS but won't do it automatically (I assume if I just reboot the network or firewall service it will also work), this isn't a problem when i am available to reboot but if i am away and unavailable the office is without phones. I had this issue on community ClerOS 6 and now i am on a trial of the latest ClearOS 7.5 Business thinking the propitiatory code might fix this as i plan to buy it anyway but the problem still persists. It is the only thing i have ever had an issue with using ClearOS over the last 6 years. Can someone try point me in the right direction of where to start looking for the problem. It's as if ClearOS is not closing the SIP ports initiated on WAN 1. If i test this by plugging out Wan1 and put it back after 5 mins or so the phones instantly work again. Other internet traffic is not affected as browsing, mails etc continue to work without users even noticing. It just refuses to route the SIP signaling after WAN change. Side note if after a reboot while sip is running fine on WAN2 if WAN2 goes down the same thing happens and SIP traffic doesn't automatically switch to WAN 1 until another reboot.
