Far right groups are planning further marches in Dover sparking fears of more violent clashes.
A Facebook event, set up by the right wing Pie and Mash Squad, has already attracted more than 100, with a further 100 expressing interest in attending marches on April 2 and St George's Day, April 23.
Representatives from other right wing factions, including the EDL and National Front, have also signaled their support.
The April 2 march is being organised by the South East Alliance, a group that describes itself as "angry, white and proud."
Left wing organisations say they will again attempt to thwart the marches, holding rival demonstrations in the town centre.
On Facebook, Kent Anti-Racism Network has set up an event called No Neo-Nazis in Dover
On the event page, the group wrote: "We now see across Europe a climate of bigotry and hatred is on the rise – the scapegoating of migrants, attacks on the Muslim community and an increase in antisemitism.
"So, on Saturday, April 2, we will take to the streets in peaceful united protest to declare Never Again - Stop the Nazis marching.
"We urge everyone to join with us to send our message loud and strong: the neo-Nazi SEA and friends are never welcome here."
Thirty people have now been arrested in connection with the protests.
In bloody scenes on January 30, several people were injured by missiles as hundreds of police attempted to separate the rival protesters.
Officers seized 20 weapons during the demonstration, including a lock-knife, knuckle duster, metal poles, pieces of wood, glass, hammers and bricks.
Police told KentOnline they have received no official notification of the demos but are monitoring the situation.
