+Subject: [PATCH] Pass ipcp-accept-remote to pppd
+
+Since https://github.com/ppp-project/ppp/commit/9fe8923419a954fedf8b6d1a6cc07b45f165c1ab,
+pppd refuses to accept a different remote IP if we explictly pass one on
+the command line. This results in an error like:
+
+pppd: Peer refused to agree to his IP address
+
+Passing ipcp-accept-remote disables this behavior.
