Ok here is the deal , I have 2 Juniper ssg-5 serial firewalls in 2 different sites connected via a VPN. Tomorrow morning the T1 circuit at our remote site will be replaced and the configured IP addresses will be changed. That said, I would like to know if the procedure written below is the only thing I have to do to have the firewall up and running after the new circuit is installed.
On my remote site (where the T1 will be changed)
1) change the Untrust ethernet0/0 interface to the New IP address and mask.
On my local site
1) Go to VPNs -> AutoKey Advanced -> Gateway
2) click on edit in the VPN pointing to the remote site (the only vpn we have) and change the static address to the new IP assigned to the remote site.
I think this should cover it but I just want to make sure.
