=== TCPFix ===
 
[[File:LineOptionsTCPFix.png|none|frame|Modifies the MSS in TCP packets so that it does not exceed the MRU.]]
 
=== MRUFix ===
 
[[File:LineOptionsMRUFix.png|none|frame|When sending IP traffic, ignore the MRU we receive during PPP negotiation. This can save a LCP re-negotiation, which has been known to help OpenBSD based PPP.]]
 
=== LCPFix ===
 
[[File:LineOptionsLCPFix.png|none|frame|Re-negotiates PPP LCP after acquiring the connection from BT, who may provide an MTU of 1500 when it should be 1492.]]
 
'''More Info:''' During the PPP connection when your router initially syncs up and logs in to us, the PPP connection is passed via BT. Sometimes BT can change the MTU. With this option we will accept the PPP connection from BT, but will then re-negotiate the PPP connection with your router allowing the MTU to be reduced. On TalkTalk connections the MTU is always negotiated as 1492, you need to select LCPFix and an MTU of 1500 to fix this, otherwise the LNS will use 1492 when re-negotiating.
